Engineers at Caltech have shown that atoms in optical cavities-tiny boxes for light-could be foundational to the creation of a quantum internet. [31] An international group of researchers, including UvA physicist Michael Walter, have devised new methods to create interesting input states for quantum computations and simulations. [29] Scientists used spiraling X-rays at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) to observe, for the first time, a property that gives handedness to swirling electric patterns-dubbed polar vortices-in a synthetically layered material. [28] To build tomorrow's quantum computers, some researchers are turning to dark excitons, which are bound pairs of an electron and the absence of an electron called a hole. [27] Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) have now achieved a major breakthrough: they demonstrated the long-lived storage of a photonic qubit on a single atom trapped in an optical resonator. [26] Achieving strong light-matter interaction at the quantum level has always been a central task in quantum physics since the emergence of quantum information and quantum control. [25] Operation at the single-photon level raises the possibility of developing entirely new communication and computing devices, ranging from hardware random number generators to quantum computers. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22] Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. [21]

UNSW material scientists have shed new light on a promising new way to store and process information in computers and electronic devices that could significantly cut down the energy required to maintain our digital lifestyles. [34] Now a team has succeeded in measuring the dynamics of these skyrmions in detail for the first time using a single-crystal sample of Cu2OSeO3. [33] Skyrmions are formed in magnetic systems via a variety of mechanisms, some of which work together. [32] Unique physical properties of these "magic knots" might help to satisfy demand for IT power and storage using a fraction of the energy. [31] A skyrmion is the magnetic version of a tornado which is obtained by replacing the air parcels that make up the tornado by magnetic spins, and by scaling the system down to the nanometre scale. [30] A new material created by Oregon State University researchers is a key step toward the next generation of supercomputers. [29] Magnetic materials that form helical structures-coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule-occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors-sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields. [27] At Carnegie Mellon University, Materials Science and Engineering Professor Mike McHenry and his research group are developing metal amorphous nanocomposite materials (MANC), or magnetic materials whose nanocrystals have been grown out of an amorphous matrix to create a two phase magnetic material that exploits both the attractive magnetic inductions of the nanocrystals and the large electrical resistance of a metallic glass. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25]

The original Maxwell equations consisted of more than a dozen equations, which have been continuously simplified into four current equations. If the existence of virtual space-time is taken into account, the existing Maxwell equations will increase to eight. This article attempts to further simplify Maxwell's equations based on virtual space-time, and finds that four of them can be derived from the other four equations. Therefore, Maxwell's equations based on virtual space-time can be simplified into four more general forms. Using the simplified Maxwell equations, the inverse square relationship of the electrostatic field strength can be derived.

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. [26] With novel optoelectronic chips and a new partnership with a top silicon-chip manufacturer, MIT spinout Ayar Labs aims to increase speed and reduce energy consumption in computing, starting with data centers. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

Any realist model of an atom must explain its properties in terms of its parts: the electrons and protons. We, therefore, need a realist model of an electron and a proton. Such model must explain their properties, including their mass, radius and magnetic moment – and the anomaly therein, of course. Indeed, these properties are not to be thought of as mysterious intrinsic properties of a pointlike or dimensionless particle: the model should generate them. We think our ring current model does that rather convincingly.
In this paper, we take the next logical step. We relate these models to the four quantum numbers that define electron orbitals. In the process, we also offer the basics of a classical explanation of the Lamb shift. This should complete our realist interpretation of quantum physics.

A study team has grown an Er3 +-doped lutetium scandium gallium garnet crystal with high doping concentration. [17] For the first time, researchers have fabricated high-performance mid-infrared laser diodes directly on microelectronics-compatible silicon substrates. [16] High-repetition-rate pulsed lasers serve a wide range of applications, from optical communications to microwave photonics and beyond. [15] Researchers have demonstrated a new all-optical technique for creating robust second-order nonlinear effects in materials that don't normally support them. [14] A research team led by physicists at LMU Munich reports a significant advance in laser-driven particle acceleration. [13] And now, physicists at and their collaborators have demonstrated that computers are ready to tackle the universe's greatest mysteries. [12] The Nuclear Physics with Lattice Quantum Chromodynamics Collaboration (NPLQCD), under the umbrella of the U.S. Quantum Chromodynamics Collaboration, performed the first model-independent calculation of the rate for proton-proton fusion directly from the dynamics of quarks and gluons using numerical techniques. [11] Nuclear physicists are now poised to embark on a new journey of discovery into the fundamental building blocks of the nucleus of the atom. [10] The drop of plasma was created in the Large Hadron Collider (LHC). It is made up of two types of subatomic particles: quarks and gluons. Quarks are the building blocks of particles like protons and neutrons, while gluons are in charge of the strong interaction force between quarks. The new quark-gluon plasma is the hottest liquid that has ever been created in a laboratory at 4 trillion C (7 trillion F). Fitting for a plasma like the one at the birth of the universe. [9] Taking into account the Planck Distribution Law of the electromagnetic oscillators, we can explain the electron/proton mass rate and the Weak and Strong Interactions. Lattice QCD gives the same results as the diffraction patterns of the electromagnetic oscillators, explaining the color confinement and the asymptotic freedom of the Strong Interactions.

"The light accumulation achieved by the light funnel could be the basis for improving the sensitivity of optical detectors and thus enabling unprecedented optical applications," Thomale explains. [43] A team from the Department of Energy's Oak Ridge National Laboratory has conducted a series of experiments to gain a better understanding of quantum mechanics and pursue advances in quantum networking and quantum computing, which could lead to practical applications in cybersecurity and other areas. [42] Counter to intuition, in a new counterfactual communication protocol published in NPJ Quantum Information, scientists from the University of Vienna, the University of Cambridge and the MIT have experimentally demonstrated that in quantum mechanics this is not always true, thereby contradicting a crucial premise of communication theory. [41] One of these particles of light has the potential to serve as a carrier of the fragile quantum information, the other, as a messenger to provide prior notification of its twin. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers. [38] Calculations of a quantum system's behavior can spiral out of control when they involve more than a handful of particles. [37] Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. [36]

Deep inside computer chips, tiny wires made of gold and other conductive metals carry the electricity used to process data. [32] A RUDN chemist has synthesized an electrocatalyst based on gold nanoparticles with organic ligands that can trigger both hydrogen production reactions and oxygen reduction reactions in fuel cells. [31] Freestanding clusters of 20 gold atoms take the shape of a pyramid, researchers have discovered. [30] The multimodal nanoscience approach to studying quantum physics phenomena is, they say, a "technological leap for how scientists can explore quantum materials to unearth new phenomena and guide future functional engineering of these materials for real-world applications." [29] Researchers have developed a three-dimensional dynamic model of an interaction between light and nanoparticles. [28] Scientists from ITMO University have developed effective nanoscale light sources based on halide perovskite. [27] Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22]

Scientists have developed a way of extracting a richer palette of colours from the available spectrum by harnessing disordered patterns inspired by nature that would typically be seen as black. [31] At the heart of his field of nonlinear optics are devices that change light from one color to another-a process important for many technologies within telecommunications, computing and laser-based equipment and science. [30] Researchers from Siberian Federal University and Kirensky Institute of Physics have proposed a new design for a multimode stripline resonator. [29] In addition to helping resolve many of the technical challenges of non-line-of-sight imaging, the technology, Velten notes, can be made to be both inexpensive and compact, meaning real-world applications are just a matter of time. [28] Researchers in the Department of Physics of ETH Zurich have measured how electrons in so-called transition metals get redistributed within a fraction of an optical oscillation cycle. [27] Insights from quantum physics have allowed engineers to incorporate components used in circuit boards, optical fibers, and control systems in new applications ranging from smartphones to advanced microprocessors. [26] In a paper published August 1, 2019 as an Editors' Suggestion in the journal Physical Review Letters, scientists at JQI and Michigan State University suggest that certain materials may experience a spontaneous twisting force if they are hotter than their surroundings. [25] The technology could allow for new capabilities in quantum computing, including modems that link together many quantum computers at different locations. [24] A University of Oklahoma physicist, Alberto M. Marino, is developing quantum-enhanced sensors that could find their way into applications ranging from biomedical to chemical detection. [23] A team of researchers from Shanghai Jiao Tong University and the University of Science and Technology of China has developed a chip that allows for two-dimensional quantum walks of single photons on a physical device.

Richard Feynman suggested anti-particles behave like they are traveling back in time. We think that is nonsense: in a ring current model, one distinguishes matter and anti-matter by the direction of travel of the charge inside. That is all. Using (or abusing) Minkowski’s notation, we may say the spacetime signature of an electron (or an antiproton) is + --- while that of a positron (or proton) would be + +++.
Indeed, in the ring current model of matter-particles, the magnetic moment alone does not allow one to distinguish between an electron with spin up and a positron with spin down. All we know is that the current that generates the magnetic moment must be different: one carries a negative charge, and the other carries a positive charge – and the direction of the physical current (the motion of the zbw charge) is opposite. The question then becomes: what distinguishes the positive and a negative zbw charge inside the zbw electron and positron?
We suggest that the assumption of a (finite) fractal structure, in which the zbw charge itself also spins, may provide a logical answer to that question.
The second topic of this paper are ‘other questions’ on the ring current model. Indeed, we all do have a number of philosophical or conceptual questions on the ring current model, which we thought we might, perhaps, insert in this paper – if only because we didn’t quite know where to put them else.

This work proposes a novel methodology for the characterization of light-matter interaction at atomic size, and may have important technological implications for the development of chemical sensors of single molecules, new sources of single or interlaced photons or nanolasers that are active at extremely low pumping powers. [37] Researchers from Würzburg and London have succeeded in controlling the coupling of light and matter at room temperature. [36] Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving cars and trucks. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32] It may seem like such optical behavior would require bending the rules of physics, but in fact, scientists at MIT, Harvard University, and elsewhere have now demonstrated that photons can indeed be made to interact-an accomplishment that could open a path toward using photons in quantum computing, if not in light sabers. [31] Optical highways for light are at the heart of modern communications. But when it comes to guiding individual blips of light called photons, reliable transit is far less common. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28]

Quantum entanglement has recently been demonstrated in macroscopic structures at the scale of microns. The densely-packed chromatin that efficiently stores DNA strands may allow for gene expression through epigenetic modifiers within the close proximity of nearby strands and may also experience gene expression through quantum entanglement of epigenetic modifiers. Such an approach may have an evolutionary advantage in the densely packed realm of chromatin.

In SunQM-3 series, we studied Solar {N,n} QM within the boundary of the traditional Schrodinger equation/solution and Born’s rule. In SunQM-4 series, we start to relax that boundary. In the current paper, for a planet in nLL QM state doing circular orbital movement, we deduced out (a full-QM deduced) |Φ(φ)|^2 * |T(t)|^2 for a planet’s time-dependent probability density in φ-dimension. To satisfy the well-known QM rule that a matter wave’s group velocity equals to 2x of its phase velocity, we have to define a non-Born calculation as |T(t)|^2 ∝ [exp(-i * ω(n,ph) * t)]^2 where ω(n,ph) is the phase angular frequency of a planet’s matter wave in φ-dimension. To obtain a physical meaningful |Φ(φ)|^2 * |T(t)|^2, we have to define a non-Born probability (NBP) density calculation as |Φ(φ)|^2 ∝ Φ(φ), or its φ-dimensional probability density function is directly proportional to its matter wave function. Combining with SunQM-3s11’s result, we built a complete Solar system with time-dependent circular orbital movement using the full-QM deduced non-Born probability density 3D map. This 3D probability density described a Solar system not only at planet’s Eigen description level, but also at any level of resolution (down to proton level, or up to the whole universe level). Therefore, we propose that “Simultaneous-Multi-Eigen-Description (SMED)” is one of many nature attributes of QM. We believe that by adding the non-Born calculation to Born calculation, the QM will become more self-consistent and more complete.

Researchers at the University of Twente and Beijing Normal University have recently conducted a study investigating the parameter known as spin memory loss (SML) for a variety of different interfaces, using a combination of theoretical and computational methods. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22] A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark.

Hence, state-of-the-art OIHP photodetectors can accelerate the translation of solution-processed photodetector applications from the laboratory to the imaging market. [31] University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices. [30] KU Leuven researchers from the Roeffaers Lab and the Hofkens Group have now put forward a very promising direct X-ray detector design, based on a rapidly emerging halide perovskite semiconductor, with chemical formula Cs2AgBiBr6. [29] Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have proven that incoming light causes the electrons in warm perovskites to rotate, thus influencing the direction of the flow of electrical current. [28] Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

Scientists of Far Eastern Federal University (FEFU, Vladivostok, Russia) together with colleagues from the Chinese Academy of Sciences (Beijing) have designed a platinum-cobalt-magnesium oxide microstructure coated by platinum that is capable of operating in three-valued logic mode (true/false/don't know). [29] Two research groups from ETH Zurich have developed a method that can simulate nanoelectronics devices and their properties realistically, quickly and efficiently. [28] Dispersible electrodes based on gold-coated magnetic nanoparticles modified with DNA can detect microRNA in unprocessed blood samples at extremely low concentrations and over a broad range-a first for sensors of this kind. [27] Engineers at the University of California San Diego have developed neutrophil "nanosponges" that can safely absorb and neutralize a variety of proteins that play a role in the progression of rheumatoid arthritis. [26] An international team of researchers has determined the function of a new family of proteins associated with cancer and autism. [25] In 2016, when we inaugurated our new IBM Research lab in Johannesburg, we took on this challenge and are reporting our first promising results at Health Day at the KDD Data Science Conference in London this month. [24] The research group took advantage of a system at SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) that combines machine learning-a form of artificial intelligence where computer algorithms glean knowledge from enormous amounts of data-with experiments that quickly make and screen hundreds of sample materials at a time. [23] Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance microscopic details in photos taken by smartphones. [22] Such are the big questions behind one of the new projects underway at the MIT-IBM Watson AI Laboratory, a collaboration for research on the frontiers of artificial intelligence. [21] The possibility of cognitive nuclear-spin processing came to Fisher in part through studies performed in the 1980s that reported a remarkable lithium isotope dependence on the behavior of mother rats.

Engineers at the Tokyo Tech have found a new approach to taking a measurement over an extended area. The technique is based on coupled chaotic oscillators, which are highly sensitive electronic circuits that can interact wirelessly through low-frequency, low-power electromagnetic coupling. [38] A cheap, biocompatible white powder that luminesces when heated could be used for non-invasively monitoring the temperature of specific organs within the body. [37] The Internet of Things (IoT) is a technology classification that includes home appliances and other items embedded with electronics, software, sensors, and actuators that connect and exchange data. One key IoT technology is optical fiber sensing.

Imagine shrinking a microscope, integrating it with a chip and using it to observe inside living cells in real time. [33] Optical scintillation imaging is proving feasible as a quality assurance (QA) tool for small static beams and for pre-treatment verification of radiosurgery and volumetric-modulated arc therapy (VMAT) plans. [32] Tweaking the design of microring sensors enhances their sensitivity without adding more implementation complexity. [31] Large-scale plasmonic metasurfaces could find use in flat panel displays and other devices that can change colour thanks to recent work by researchers at the University of Cambridge in the UK. [30] Particles in solution can grow, transport, collide, interact, and aggregate into complex shapes and structures.

Researchers at Los Alamos National Laboratory are reinventing the mirror, at least for microwaves, potentially replacing the familiar 3-D dishes and microwave horns we see on rooftops and cell towers with flat panels that are compact, versatile, and better adapted for modern communication technologies. [52] Researchers from the University of Tokyo developed a new system to charge electronic devices such as smartphones and smartwatches wirelessly. [51] The ultrathin digital camera offers a wide field of view and high resolution in a slimmer body compared to existing imaging systems. [50] The special feature of the Kiel system is its extremely high temporal resolution of 13 femtoseconds. [49] Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. [48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices. [47] In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that can repair or heal itself after damage. [46] A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks. [45] Graphene-based computer components that can deal in terahertz "could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates," Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds. [44] Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. [43]

"We invoke a different theory, the self-interacting dark matter model or SIDM, to show that dark matter self-interactions thermalize the inner halo, which ties ordinary dark matter and dark matter distributions together so that they behave like a collective unit." [23] Technology proposed 30 years ago to search for dark matter is finally seeing the light. [22] They're looking for dark matter-the stuff that theoretically makes up a quarter of our universe. [21] Results from its first run indicate that XENON1T is the most sensitive dark matter detector on Earth. [20] Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have now come up with a new theory on how dark matter may have been formed shortly after the origin of the universe. [19] Map of dark matter made from gravitational lensing measurements of 26 million galaxies in the Dark Energy Survey. [18] CfA astronomers Annalisa Pillepich and Lars Hernquist and their colleagues compared gravitationally distorted Hubble images of the galaxy cluster Abell 2744 and two other clusters with the results of computer simulations of dark matter haloes. [17] In a paper published July 20 in the journal Physical Review Letters, an international team of cosmologists uses data from the intergalactic medium-the vast, largely empty space between galaxies-to narrow down what dark matter could be. [16] But a new hypothesis might have gotten us closer to figuring out its identity, because physicists now suspect that dark matter has been changing forms this whole time-from ghostly particles in the Universe's biggest structures, to a strange, superfluid state at smaller scales. And we might soon have the tools to confirm it. [15] Superfluids may exist inside neutron stars, and some researchers have speculated that space-time itself may be a superfluid. So why shouldn't dark matter have a superfluid phase, too? [14] "The best result on dark matter so far-and we just got started." This is how scientists behind XENON1T, now the most sensitive dark matter experiment worldwide , commented on their first result from a short 30-day run presented today to the scientific community. [13] The gravitational force attracting the matter, causing concentration of the matter in a small space and leaving much space with low matter concentration: dark matter and energy. There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnetic radiations being in the same intensity level and compensating each other. One of these compensating ratios is the electron-proton mass ratio. The lower energy side has no compensating intensity level, it is the dark energy and the corresponding matter is the dark matter. SIMPs would resolve certain discrepancies between simulations of the distribution of dark matter, like this one, and the observed properties of the galaxies. In particle physics and astrophysics, weakly interacting massive particles, or WIMPs, are among the leading hypothetical particle physics candidates for dark matter.

Markus Koch, head of the research group Femtosecond Dynamics at the Institute of Experimental Physics at TU Graz, and his team develop new methods for time-resolved femtosecond laser spectroscopy to investigate ultrafast processes in molecular systems. [21] Each individual molecule can conduct electrons. This phenomenon is interesting because the conducting molecules produce unique quantum properties that could potentially be useful in electronics such as transistors, superconducting switches and gas sensors. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18] Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. [17] Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations. [16] Physicists have proposed a new type of Maxwell's demon-the hypothetical agent that extracts work from a system by decreasing the system's entropy-in which the demon can extract work just by making a measurement, by taking advantage of quantum fluctuations and quantum superposition. [15] Pioneering research offers a fascinating view into the inner workings of the mind of 'Maxwell's Demon', a famous thought experiment in physics. [14] For more than a century and a half of physics, the Second Law of Thermodynamics, which states that entropy always increases, has been as close to inviolable as any law we know. In this universe, chaos reigns supreme. [13] Physicists have shown that the three main types of engines (four-stroke, twostroke, and continuous) are thermodynamically equivalent in a certain quantum regime, but not at the classical level.

Now, Harvard and MIT researchers have found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. [28] This proposal represents a new step towards quantum information networks, since it sets a solid theoretical framework on what is physically possible in the field of automated classification and distribution of quantum information. [27] Researchers from QuTech have achieved a world's first in quantum internet technology. [26] The achievement represents a major step towards a "quantum internet," in which future computers can rapidly and securely send and receive quantum information. [25] Scientists have used precisely tuned pulses of laser light to film the ultrafast rotation of a molecule. [24] Recently, researchers have been investigating how these quantum fingerprints might one day be used as an inexpensive form of ID to protect users' personal information for technologies in the emerging network of internet-connected devices known as the Internet of Things.

Lin has been working to establish this advance for 17 years, since he created the first all-metallic photonic crystal in 2002, and the two papers represent the most rigorous tests he has conducted. [29] This interference is important for everything from fundamental tests of quantum physics to the speedy calculations of quantum computers, but creating it requires exquisite control over particles that are indistinguishable. [28] Scientists from the Faculty of Physics, University of Warsaw, in collaboration with the University of Oxford and NIST, have shown that quantum interference enables processing of large sets of data faster and more accurately than with standard methods. [27] Over the last few decades, the exponential increase in computer power and accompanying increase in the quality of algorithms has enabled theoretical and particle physicists to perform more complex and precise simulations of fundamental particles and their interactions. [26] A collaboration of scientists from five of the world's most advanced x-ray sources in Europe, Japan and the US, has succeeded in verifying a basic prediction of the quantum-mechanical behavior of resonant systems. [25] This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22] Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. [21] Engineers at Australia's University of New South Wales have invented a radical new architecture for quantum computing, based on novel 'flip-flop qubits', that promises to make the large-scale manufacture of quantum chips dramatically cheaper-and easier-than thought possible.

Exotic phases of matter known as spin ices are defined by frustrated spins that obey local "ice rules"-similar to electric dipoles in water ice. [20] Nuclear techniques at ANSTO have helped to confirm a quantum spin phenomena, a Haldane phase, in a magnetic material, that has potential to be used as a measurement model for quantum computation. [19] Lithium-ion batteries could be under threat after the development of polymer materials by the Universities of Surrey and Bristol, along with Superdielectrics Ltd, that could challenge the dominance of these traditional batteries. [18] Researchers from Umeå University and Linköping University in Sweden have developed light-emitting electrochemical cells (LECs) that emit strong light at high efficiency. As such, the thin, flexible and lightweight LEC promises future and improved applications within home diagnostics, signage, illumination and healthcare. [17] Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons-particles of light-interact and change direction. [16] In materials research, chemistry, biology, and medicine, chemical bonds, and especially their dynamic behavior, determine the properties of a system. These can be examined very closely using terahertz radiation and short pulses. [15] An international collaborative of scientists has devised a method to control the number of optical solitons in microresonators, which underlie modern photonics. [14] Solitary waves called solitons are one of nature's great curiosities: Unlike other waves, these lone wolf waves keep their energy and shape as they travel, instead of dissipating or dispersing as most other waves do. In a new paper in Physical Review Letters (PRL), a team of mathematicians, physicists and engineers tackles a famous, 50-year-old problem tied to these enigmatic entities. [13] Theoretical physicists studying the behavior of ultra-cold atoms have discovered a new source of friction, dispensing with a century-old paradox in the process. Their prediction, which experimenters may soon try to verify, was reported recently in Physical Review Letters. [12] Solitons are localized wave disturbances that propagate without changing shape, a result of a nonlinear interaction that compensates for wave packet dispersion.

A team led by Prof. Guo Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) and collaborators first realized distribution of high-dimensional orbital angular momentum entanglement over a 1 km few-mode fiber. [56] A happy accident in the laboratory has led to a breakthrough discovery that not only solved a problem that stood for more than half a century, but has major implications for the development of quantum computers and sensors. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation. [52] Australian scientists have investigated new directions to scale up qubits-utilising the spin-orbit coupling of atom qubits-adding a new suite of tools to the armory. [51] A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories. [50] Working in the lab of Mikhail Lukin, the George Vasmer Leverett Professor of Physics and co-director of the Quantum Science and Engineering Initiative, Evans is lead author of a study, described in the journal Science, that demonstrates a method for engineering an interaction between two qubits using photons. [49] Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information.

Honeywell says that it will release the world's most powerful commercial quantum computer by mid-2020. [36] US manufacturing and technology group Honeywell said Tuesday it will bring to market "the world's most powerful quantum computer" aimed at tackling complex scientific and business challenges. [35] New research gives insight into a recent experiment that was able to manipulate an unprecedented number of atoms through a quantum simulator. This new theory could provide another step on the path to creating the elusive quantum computers. [34] Chinese scientists Xianmin Jin and his colleagues from Shanghai Jiao Tong University have successfully fabricated the largest-scaled quantum chip and demonstrated the first two-dimensional quantum walks of single photons in real spatial space, which may provide a powerful platform to boost analog quantum computing for quantum supremacy. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [29] Magnetic materials that form helical structures-coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule-occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices.

In the future, Army scientists will investigate methods to continue to improve the sensitivity to detect even weaker signals and expand detection protocols for more complicated waveforms. A team of researchers with members from IBM Research-Zurich and RWTH Aachen University has announced the development of a new PCM (phase change memory) design that offers miniaturized memory cell volume down to three nanometers. [18] Monatomic glassy antimony might be used as a new type of single-element phase change memory. [17] Physicists have designed a 3-D quantum memory that addresses the tradeoff between achieving long storage times and fast readout times, while at the same time maintaining a compact form. [16] Quantum memories are devices that can store quantum information for a later time, which are usually implemented by storing and re-emitting photons with certain quantum states. [15] The researchers engineered diamond strings that can be tuned to quiet a qubit's environment and improve memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip. [14] Intel has announced the design and fabrication of a 49-qubit superconducting quantum-processor chip at the Consumer Electronics Show in Las Vegas.

While beam steering systems have been used for many years for applications such as imaging, display, and optical trapping, they require bulky mechanical mirrors and are overly sensitive to vibrations. [28] Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. [27] Bendable light beams have significant applications in optical manipulation, optical imaging, routing, micromachining and nonlinear optics. [26] Karimi's team has successfully built and operated the first-ever quantum simulator designed specifically for simulating cyclic (ringed-shaped) systems. [25] A new Tel Aviv University study explores the generation and propagation of excitons in 2D materials within an unprecedented small time frame and at an extraordinarily high spatial resolution. [24] An international team of researchers led out of Macquarie University has demonstrated a new approach for converting ordinary laser light into genuine quantum light. [23] Beyond the beauty of this phenomenon, which connects heating processes to topology through an elegant quantization law, the results reported in this work designate heating measurements as a powerful and universal probe for exotic states of matter.

And finally to better understand the cause of the reversible refractive index changes, the researchers examined variations in the structure of a 1-dimensional membrane where the main contributor to the switching states of the MRR device is shown to be metastable volumetric expansion. [33] Researchers have created a silicon carbide (SiC) photonic integrated chip that can be thermally tuned by applying an electric signal. [32] Compact quantum devices could be incorporated into laptops and mobile phones, thanks in part to small devices called quantum optical micro-combs. [31] Taking their name from an intricate Japanese basket pattern, kagome magnets are thought to have electronic properties that could be valuable for future quantum devices and applications. [30] A team of Cambridge researchers have found a way to control the sea of nuclei in semiconductor quantum dots so they can operate as a quantum memory device. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22]

They will then use the fiber-optic network in place around the city of Bristol to create a demonstration metropolitan network with many users. [44] Quantum secure direct communication (QSDC) is an important branch of quantum communication, based on the principles of quantum mechanics for the direct transmission of classified information. [43] The deluge of cyberattacks sweeping across the world has governments and companies thinking about new ways to protect their digital systems, and the corporate and state secrets stored within. [42] The Pentagon on Friday said there has been a cyber breach of Defense Department travel records that compromised the personal information and credit card data of U.S. military and civilian personnel. [41] Quantum secure direct communication transmits secret information directly without encryption. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers. [38] Calculations of a quantum system's behavior can spiral out of control when they involve more than a handful of particles. [37] Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. [36]

Researchers from the Zepler Institute for Photonics and Nanoelectronics at the University of Southampton have demonstrated a new leap in hollow-core fiber performance, underlining the technology's potential to soon eclipse current optical fibers. [36] A fiber optic sensing system developed by researchers in China and Canada can peer inside supercapacitors and batteries to observe their state of charge. [35] The idea of using a sound wave in optical fibers initially came from the team's partner researchers at Bar-Ilan University in Israel. Joint research projects should follow. [34] Researchers at the Technion-Israel Institute of Technology have constructed a first-of-its-kind optic isolator based on resonance of light waves on a rapidly rotating glass sphere. [33] The micro-resonator is a two-mirror trap for the light, with the mirrors facing each other within several hundred nanometers. [32] "The realization of such all-optical single-photon devices will be a large step towards deterministic multi-mode entanglement generation as well as high-fidelity photonic quantum gates that are crucial for all-optical quantum information processing," says Tanji-Suzuki. [31] Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. [30] A new benchmark quantum chemical calculation of C2, Si2, and their hydrides reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues. [29] A University of Central Florida team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality-a property of molecular spatial twist that defines its biochemical properties. [28] UCLA scientists and engineers have developed a new process for assembling semiconductor devices. [27]

To understand the behavior of quantum particles, imagine a pinball game-but rather than one metal ball, there are billions or more, all ricocheting off each other and their surroundings. [30] In quantum physics, some of the most interesting effects are the result of interferences. [29] When Nebraska's Herman Batelaan and colleagues recently submitted a research paper that makes the case for the existence of a non-Newtonian, quantum force, the journal asked that they place "force" firmly within quotes.

Over the past few years, scientists have developed amazing tools-"cameras" that use X-rays or electrons instead of ordinary light ¬-to take rapid-fire snapshots of molecules in motion and string them into molecular movies. [39] A research team from ITMO University, with the help of colleagues from MIPT (Russia) and Politecnico di Torino (Italy), has predicted a novel type of topological quantum state of two photons. [38] A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. [37] Researchers have demonstrated the first quantum light-emitting diode (LED) that emits single photons and entangled photon pairs with a wavelength of around 1550 nm, which lies within the standard telecommunications window. [36] JILA scientists have invented a new imaging technique that produces rapid, precise measurements of quantum behavior in an atomic clock in the form of near-instant visual art. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32] It may seem like such optical behavior would require bending the rules of physics, but in fact, scientists at MIT, Harvard University, and elsewhere have now demonstrated that photons can indeed be made to interact-an accomplishment that could open a path toward using photons in quantum computing, if not in light sabers. [31] Optical highways for light are at the heart of modern communications. But when it comes to guiding individual blips of light called photons, reliable transit is far less common. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29]

Optical multiplexing and demultiplexing utilizing the intrinsic physical properties of light has played a crucial role in high-capacity data storage and high-speed communications. [37] Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. [36] The key technical novelty of this work is the creation of semantic embeddings out of structured event data. [35] The researchers have focussed on a complex quantum property known as entanglement, which is a vital ingredient in the quest to protect sensitive data. [34] Cryptography is a science of data encryption providing its confidentiality and integrity. [33] Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure.

"We will be able to test the output of quantum computers against these calculations," said Krishnamoorthy. "If quantum computers can produce results close to these results, we will know they work." [57] We all learn quantum physics as physics students, but in recent years this field has taken on a whole new life. It's not an esoteric theory anymore, something that only describes tiny effects in extreme forms of matter. It's going to form the basis for a whole new type of technology. So I think that, because physicists have a bit of a leg up in this area, they should go all-in. [56] Scientists from the University of Bath, working with a colleague at the Bulgarian Academy of Sciences, have devised an ingenious method of controlling the vapour by coating the interior of containers with nanoscopic gold particles 300,000 times smaller than a pinhead. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation. [52] Australian scientists have investigated new directions to scale up qubits-utilising the spin-orbit coupling of atom qubits-adding a new suite of tools to the armory. [51]

The researchers are now preparing optical lattice clocks to demonstrate a clock network using this fiber link and are working to make electrical components of the system more practical. [21] Researchers at Northwestern University, the University of Bath, and the University of Sydney have developed a new network approach to topic models, machine learning strategies that can discover abstract topics and semantic structures within text documents. [20] To achieve remarkable results in computer vision tasks, deep learning algorithms need to be trained on large-scale annotated datasets that include extensive informationabout every image. [19] Brian Mitchell and Linda Petzold, two researchers at the University of California, have recently applied model-free deep reinforcement learning to models of neural dynamics, achieving very promising results.

The results suggest the higher Tc in CuxBi2Se3 could be further achieved by gating-technique or high pressure technique, as realized in iron-selenides superconductors. [29] A superconductor can switch the magnetic moment of a single-molecule magnet placed on top of it. [28] Discovered more than 100 years ago, superconductivity continues to captivate scientists who seek to develop components for highly efficient energy transmission, ultrafast electronics or quantum bits for next-generation computation. [27] One of the greatest mysteries in condensed matter physics is the exact relationship between charge order and superconductivity in cuprate superconductors. [26] Cuprates hold the record high superconducting temperature at ambient pressure so far, but understanding their superconducting mechanism remains one of the great challenges of physical sciences listed as one of 125 quests announced by Science. [25] Now, scientists at Tokyo Institute of Technology (Tokyo Tech), the University of Tokyo and Tohoku University report curious multi-state transitions of these superconductors in which they change from superconductor to special metal and then to insulator. [24] Researchers at the Zavoisky Physical-Technical Institute and the Southern Scientific Center of RAS, in Russia, have recently fabricated quasi-2-D superconductors at the interface between a ferroelectric Ba0.8Sr0.2TiO3 film and an insulating parent compound of La2CuO4. [23] Scientists seeking to understand the mechanism underlying superconductivity in "stripe-ordered" cuprates-copper-oxide materials with alternating areas of electric charge and magnetism-discovered an unusual metallic state when attempting to turn superconductivity off. [22] This discovery makes it clear that in order to understand the mechanism behind the enigmatic high temperature superconductivity of the cuprates, this exotic PDW state needs to be taken into account, and therefore opens a new frontier in cuprate research. [21] High-temperature (Tc) superconductivity typically develops from antiferromagnetic insulators, and superconductivity and ferromagnetism are always mutually exclusive. [20]

This work shows how machine learning techniques such as developed in this work could play a crucial role in this aspect of the realization of a full-scale fault-tolerant universal quantum computer-the ultimate goal of the global research effort. [26] A Cornell-led team has developed a way to use machine learning to analyze the data generated by scanning tunneling microscopy (STM)-a technique that produces subatomic scale images of electronic motions in material surfaces at varying energies, providing information unattainable by any other method. [25] Physicists in the US have used machine learning to determine the phase diagram of a system of 12 idealized quantum particles to a higher precision than ever before. [24] The research group took advantage of a system at SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) that combines machine learning-a form of artificial intelligence where computer algorithms glean knowledge from enormous amounts of data-with experiments that quickly make and screen hundreds of sample materials at a time. [23] Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance microscopic details in photos taken by smartphones. [22] Such are the big questions behind one of the new projects underway at the MIT-IBM Watson AI Laboratory, a collaboration for research on the frontiers of artificial intelligence. [21]

Scientists from NUST MISIS (Russia) together with colleagues from Sweden, Hungary and U.S., found a way to manufacture stable qubits that operate at room temperature, in contrast to the majority of existing analogues. [49] A group of physicists in Utrecht, San Sebastián and Pennsylvania have created a new artificial molecule that is insulating inside but has electronic states localized in its corners. [48] In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. [47] "Our bacterially produced graphene material will lead to far better suitability for product development," Meyer says. [46] Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. [45] Using data from the CMS experiment there, the researchers studied the entropy resulting from entanglement within the proton. [44] A German-Austrian research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of 20 quantum bits. [43] Neill is lead author of the group's new paper, "A blueprint for demonstrating quantum supremacy with superconducting qubits," now published in the journal Science. [42] Physicists at ETH Zurich have now demonstrated an elegant way to relax this intrinsic incompatibility using a mechanical oscillator formed by a single trapped ion, opening up a route for fundamental studies and practical uses alike. [41] Physical experiments were performed by Schiffer's team at the University of Illinois at Urbana-Champaign and were funded by the U.S. Department of Energy's Office of Science. [40] Novel insight comes now from experiments and simulations performed by a team led by ETH physicists who have studied electronic transport properties in a one-dimensional quantum wire containing a mesoscopic lattice.

According to `the wave-particle non-dualistic interpretation of quantum mechanics at a single-quantum level’ (NI), the SchrÖdinger wave function is proposed/shown to be an instantaneous resonant spatial mode in which a quantum moves. To verify this key proposal, a modified Mach-Zehnder interferometer experiment with a single-particle source is proposed. A negative result of this experiment simply implies that the NI is wrong.

Finally, the combination of the experimental evidence, first-principles simulations and theoretical models on 3-D jacutingaite supports THEOS's earlier prediction that 2-D jacutingaite is a Kane-Mele (graphene-like) quantum spin Hall insulator. [28] The topological QPC, first implemented at JMU Würzburg, offers an exciting perspective in this respect. [27] A certain kind of material, called a topological insulator, acts partially like one and partially like the other-it behaves like a conductor at its surface and an insulator in its interior. [26] Topological insulators (TIs) host exotic physics that could shed new light on the fundamental laws of nature. [25] A new study by scientists from the University of Bristol brings us a significant step closer to unleashing the revolutionary potential of quantum computing by harnessing silicon fabrication technology to build complex on-chip quantum optical circuits. [24] Two teams of scientists from the Technion-Israel Institute of Technology have collaborated to conduct groundbreaking research leading to the development of a new and innovative scientific field: Quantum Metamaterials. [23] An international team consisting of Russian and German scientists has made a breakthrough in the creation of seemingly impossible materials. They have created the world's first quantum metamaterial that can be used as a control element in superconducting electrical circuits. [22] ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product. [21] Cheng Chin, professor in the Department of Physics, and his team looked at an experimental setup of tens of thousands of atoms cooled down to near absolute zero. As the system crossed a quantum phase transition, they measured its behavior with an extremely sensitive imaging system. [20]

"Cryogenics should not be an obstacle that stops anyone from doing an experiment or developing an application; the measurement infrastructure should be readily available so researchers can focus on making their experiment." [43] But with a team of researchers from the UK and France, we have demonstrated that it may well be possible to build a quantum computer from conventional silicon-based electronic components. [42] Physicists at ETH Zurich have now demonstrated an elegant way to relax this intrinsic incompatibility using a mechanical oscillator formed by a single trapped ion, opening up a route for fundamental studies and practical uses alike. [41] Physical experiments were performed by Schiffer's team at the University of Illinois at Urbana-Champaign and were funded by the U.S. Department of Energy's Office of Science. [40] Novel insight comes now from experiments and simulations performed by a team led by ETH physicists who have studied electronic transport properties in a one-dimensional quantum wire containing a mesoscopic lattice. [39] Femtosecond lasers are capable of processing any solid material with high quality and high precision using their ultrafast and ultra-intense characteristics. [38] To create the flying microlaser, the researchers launched laser light into a water-filled hollow core fiber to optically trap the microparticle. Like the materials used to make traditional lasers, the microparticle incorporates a gain medium. [37] Lasers that emit ultrashort pulses of light are critical components of technologies, including communications and industrial processing, and have been central to fundamental Nobel Prize-winning research in physics. [36] A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy.

Silicon photonics are known as a key technology for modern optical communications at the near infrared wavelength-band, i.e., 1.31/1.55 μm. [31] Physicists of the University of Basel, the Paul Scherrer Institute and ABB explain what prevents the use of this combination of silicon and carbon in the scientific journal Applied Physics Letters. [30] A potentially useful material for building quantum computers has been unearthed at the National Institute of Standards and Technology (NIST), whose scientists have found a superconductor that could sidestep one of the primary obstacles standing in the way of effective quantum logic circuits. [29] Important challenges in creating practical quantum computers have been addressed by two independent teams of physicists in the US. [28] Physicists have shown that superconducting circuits-circuits that have zero electrical resistance-can function as piston-like mechanical quantum engines. The new perspective may help researchers design quantum computers and other devices with improved efficiencies. [27] This paper explains the magnetic effect of the superconductive current from the observed effects of the accelerating electrons, causing naturally the experienced changes of the electric field potential along the electric wire. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the wave particle duality and the electron's spin also, building the bridge between the Classical and Quantum Theories. The changing acceleration of the electrons explains the created negative electric field of the magnetic induction, the Higgs Field, the changing Relativistic Mass and the Gravitational Force, giving a Unified Theory of the physical forces. Taking into account the Planck Distribution Law of the electromagnetic oscillators also, we can explain the electron/proton mass rate and the Weak and Strong Interactions. Since the superconductivity is basically a quantum mechanical phenomenon and some entangled particles give this opportunity to specific matters, like Cooper Pairs or other entanglements, as strongly correlated materials and Exciton-mediated electron pairing, we can say that the secret of superconductivity is the quantum entanglement.

In this paper, we show how one can find the Compton scattering formula and thereby also the Compton wavelength based on new concepts from collision-space time. This gives us the standard Compton wavelength, but we go one step forward and show how to find the relativistic Compton wavelength from Compton scattering as well. (That is, when the electron is also moving initially.) The original Compton formula only gives the electron’s rest-mass Compton wavelength, or we could call it the standing electron’s Compton wave.

The hunt for high-temperature superconductors could be aided by calculations by RIKEN physicists that have revealed the behavior of electrons in a nickel oxide material. [26] Researchers from the University of Houston have reported a new way to raise the transition temperature of superconducting materials, boosting the temperature at which the superconductors are able to operate. [25] Some iron-based superconductors could benefit from a tuneup, according to two studies by Rice University physicists and collaborators. [24] Two teams of scientists from the Technion-Israel Institute of Technology have collaborated to conduct groundbreaking research leading to the development of a new and innovative scientific field: Quantum Metamaterials. [23] An international team consisting of Russian and German scientists has made a breakthrough in the creation of seemingly impossible materials. They have created the world's first quantum metamaterial that can be used as a control element in superconducting electrical circuits. [22] ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product. [21] Cheng Chin, professor in the Department of Physics, and his team looked at an experimental setup of tens of thousands of atoms cooled down to near absolute zero. As the system crossed a quantum phase transition, they measured its behavior with an extremely sensitive imaging system. [20] Scientists from three UK universities are to test one of the fundamental laws of physics as part of a major Europe-wide project awarded more than £3m in funding. ]19] A team of researchers has devised a simple way to tune a hallmark quantum effect in graphene-the material formed from a single layer of carbon atoms-by bathing it in light.

Researchers of the University of Basel have developed a new method with which individual isolated molecules can be studied precisely-without destroying the molecule or even influencing its quantum state. [18] The researchers have generated femtosecond laser pulses, with tailor-made, temporally varying polarizations, which are themselves chiral. [17] The scientists identified a shortlist, a kind of "periodic table" of the most designable knot types, i.e. those knots that could easily self-assemble under appropriate physical and chemical conditions. [16] Scientists have now observed for the first time how diamonds grow from seed at an atomic level, and discovered just how big the seeds need to be to kick the crystal growing process into overdrive. [15] The researchers engineered diamond strings that can be tuned to quiet a qubit's environment and improve memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip. [14] Intel has announced the design and fabrication of a 49-qubit superconducting quantum-processor chip at the Consumer Electronics Show in Las Vegas. To improve our understanding of the so-called quantum properties of materials, scientists at the TU Delft investigated thin slices of SrIrO3, a material that belongs to the family of complex oxides. [12] New research carried out by CQT researchers suggest that standard protocols that measure the dimensions of quantum systems may return incorrect numbers. [11] Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement? [10] A trio of scientists who defied Einstein by proving the nonlocal nature of quantum entanglement will be honoured with the John Stewart Bell Prize from the University of Toronto (U of T). [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. Quantum teleportation of data had been done before but with highly unreliable methods. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to build the Quantum Computer with the help of Quantum Information.

A happy accident in the laboratory has led to a breakthrough discovery that not only solved a problem that stood for more than half a century, but has major implications for the development of quantum computers and sensors. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation. [52] Australian scientists have investigated new directions to scale up qubits-utilising the spin-orbit coupling of atom qubits-adding a new suite of tools to the armory. [51] A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories. [50] Working in the lab of Mikhail Lukin, the George Vasmer Leverett Professor of Physics and co-director of the Quantum Science and Engineering Initiative, Evans is lead author of a study, described in the journal Science, that demonstrates a method for engineering an interaction between two qubits using photons. [49] Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information. [48] Researchers from Intel Corp. and the University of California, Berkeley, are looking beyond current transistor technology and preparing the way for a new type of memory and logic circuit that could someday be in every computer on the planet.

A team of researchers from the University of Regensburg and Ludwig-Maximilians-University Munich has developed a way to measure the dependence of an atom's chemical reactivity on its chemical bonds. [40] In a first for quantum physics, University of Otago researchers have "held" individual atoms in place and observed previously unseen complex atomic interactions. [39] Experiments with ultra-cold atoms at the TU Wien have shown surprising results: coupled atom clouds synchronize within milliseconds. This effect cannot be explained by standard theories. [38] Scientists forged quantum connections between separate regions within clouds of ultracold atoms, demonstrating entanglement between thousands of particles in two different locations. [37] Researchers have demonstrated the first quantum light-emitting diode (LED) that emits single photons and entangled photon pairs with a wavelength of around 1550 nm, which lies within the standard telecommunications window. [36] JILA scientists have invented a new imaging technique that produces rapid, precise measurements of quantum behavior in an atomic clock in the form of near-instant visual art. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32]

Scientists in Australia have developed a new approach to reducing the errors that plague experimental quantum computers; a step that could remove a critical roadblock preventing them scaling up to full working machines. [32] These findings raise some fundamental questions-and they're polarising experts. [31] Researchers at the RUDN University have developed a mathematical method to solve the quantum Coulomb three-body problem for bound states with high accuracy. [30] Ant-Man knows the quantum realm holds shocking revelations and irrational solutions. [29] A new uncertainty relation, linking the precision with which temperature can be measured and quantum mechanics, has been discovered at the University of Exeter. [28] Physicists have demonstrated that energy quantization can improve the efficiency of a single-atom heat engine to exceed the performance of its classical counterpart. [27] A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators-resulting in leak-free machines that can stay operating longer. [26] Like watchmakers choosing superior materials to build a fine timepiece, physicists at the Centre for Quantum Technologies (CQT) at the National University of Singapore have singled out an atom that could allow them to build better atomic clocks. [25] Yale physicists have uncovered hints of a time crystal-a form of matter that "ticks" when exposed to an electromagnetic pulse-in the last place they expected: a crystal you might find in a child's toy. [24] The research shows that concentrated electrolytes in solution affect hydrogen bonding, ion interactions, and coordination geometries in currently unpredictable ways. [23]

[31] Optical highways for light are at the heart of modern communications. But when it comes to guiding individual blips of light called photons, reliable transit is far less common. [30]

A new model that predicts the charging timescales of supercapacitors much more accurately than had been previously possible has been unveiled by researchers in the Netherlands and China. [31] Now, Sadashige Matsuo of the RIKEN Center for Emergent Matter Science and colleagues have created a device called a Josephson junction, which can efficiently split these Cooper pairs as they travel from a superconductor into two one-dimensional normal conductors. [30] Using a clever technique that causes unruly crystals of iron selenide to snap into alignment, Rice University physicists have drawn a detailed map that reveals the "rules of the road" for electrons both in normal conditions and in the critical moments just before the material transforms into a superconductor. [29] Superconducting quantum microwave circuits can function as qubits, the building blocks of a future quantum computer. [28] Physicists have shown that superconducting circuits-circuits that have zero electrical resistance-can function as piston-like mechanical quantum engines. The new perspective may help researchers design quantum computers and other devices with improved efficiencies.

The sending-or-not-sending twin-field (SNS-TF) protocol has so far proved to be a highly promising strategy for achieving high rates over long distances in quantum key distribution (QKD) applications. [17] EPFL physicist László Forró and his team pave the way for the future of data storage. [16] Researchers from the University of Toronto Engineering and King Abdullah University of Science and Technology (KAUST) have overcome a key obstacle in combining the emerging solar-harvesting technology of perovskites with the commercial gold standard-silicon solar cells. [15] Researchers from the Theory Department of the MPSD in Hamburg and North Carolina State University in the US have demonstrated that the long-sought magnetic Weyl semi-metallic state can be induced by ultrafast laser pulses in a three-dimensional class of magnetic materials dubbed pyrochlore iridates. [14] At TU Wien recently, particles known as 'Weyl fermions' were discovered in materials with strong interaction between electrons. Just like light particles, they have no mass but nonetheless they move extremely slowly. [13] Quantum behavior plays a crucial role in novel and emergent material properties, such as superconductivity and magnetism. [12] A source of single photons that meets three important criteria for use in quantum information systems has been unveiled in China by an international team of physicists. Based on a quantum dot, the device is an efficient source of photons that emerge as solo particles that are indistinguishable from each other. The researchers are now trying to use the source to create a quantum computer based on "boson sampling". [11] With the help of a semiconductor quantum dot, physicists at the University of Basel have developed a new type of light source that emits single photons. For the first time, the researchers have managed to create a stream of identical photons. [10] Optical photons would be ideal carriers to transfer quantum information over large distances. Researchers envisage a network where information is processed in certain nodes and transferred between them via photons. [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported.

"Everything the light touches is our kingdom," says doctoral student Hagai Diamandi from the Faculty of Engineering at Bar-Ilan University in Israel. [30] Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. [29] Researchers from Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, have demonstrated a 4000 kilometre fibre-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers. [28] Researchers at the University of York have shown that a new quantum-based procedure for distributing secure information along communication lines could be successful in preventing serious security breaches. [27] In the new study, Bomantara and Gong have developed a method for harnessing the unique properties of time crystals for quantum computing that is based on braiding. [26] An Aalto University study has provided new evidence that time crystals can physically exist-a claim currently under hot debate. [25] Yale physicists have uncovered hints of a time crystal-a form of matter that "ticks" when exposed to an electromagnetic pulse-in the last place they expected: a crystal you might find in a child's toy.

It should be possible to create materials that conduct both electric current and exciton excitation energy with 100% efficiency and at relatively high temperatures-according to theoretical chemists in the US. [31] New Cornell-led research is pointing the way toward an elusive goal of physicists-high-temperature superfluidity-by exploring excitons in atomically thin semiconductors. [30] After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.

[26] Achieving strong light-matter interaction at the quantum level has always been a central task in quantum physics since the emergence of quantum information and quantum control. [25] Operation at the single-photon level raises the possibility of developing entirely new communication and computing devices, ranging from hardware random number generators to quantum computers. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22] Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. [21]

K. Suto has recently pointed out an interesting relativistic extension of Rydberg's formula. Here we also discuss Rydberg's formula, and offer additional evidence on how one can easily see that it is nonrelativistic and therefore a good approximation, at best, when v<<c. We also extend the Suto formula to hold for any atom and examine the formula in detail.

In this paper, primary focus on to derive Planck particle mass . Take some formulas first wrote down on blank paper and do planning for how desired mass can be derived. Beside the way during the whole scenario, obstacles comes out such as how velocity term can be derived because i don’t know the velocity value or this is unknown yet. So i use other formula called mass variation formula to create velocity term and then put out the unknown velocity in this velocity, this will ease the calculations and our path more directed towards Planck particle mass. On the basis of derived mass, put new thoughts on Planck particle and black hole

This paper recaps the main results of our photon, proton and electron models and also revisits our earlier hypothesis of the neutrino being the carrier of the strong force carrier. As such, we think this paper contains all necessary ingredients of an alternative interpretation of quantum mechanics. We refer to this interpretation as a realist or classical interpretation because it does not require any equations or assumptions beyond the classical framework of physics: Maxwell’s equations and the Planck-Einstein relation are all that is needed. In order to distinguish our approach from mainstream physics (read: the Standard Model), we refer to our ideas as classical quantum physics.

Researchers from the Department of Energy's SLAC National Accelerator Laboratory have made a promising new advance for the lab's high-speed "electron camera" that could allow them to "film" tiny, ultrafast motions of protons and electrons in chemical reactions that have never been seen before. [40] A team of Northwestern University materials science researchers have developed a new method to view the dynamic motion of atoms in atomically thin 2-D materials. [39] Researchers led by MIT Department of Physics Professor Pablo Jarillo-Herrero last year showed that rotating layers of hexagonally structured graphene at a particular "magic angle" could change the material's electronic properties from an insulating state to a superconducting state. [38] Scientists at the University of Hong Kong and Hunan Normal University showed that, in homobilayer transition metal dichalcogenides, the real-space Berry phase from moiré patterns manifests as a periodic magnetic field. [37] In a paper published today in Nature's NPJ Quantum Information, Omar Magaña-Loaiza, assistant professor in the Louisiana State University (LSU) Department of Physics & Astronomy, and his team of researchers describe a noteworthy step forward in the quantum manipulation and control of light, which has far-reaching quantum technology applications in imaging, simulation, metrology, computation, communication, and cryptography, among other areas. [36] Scientists at Tokyo Institute of Technology have fabricated a multiplexer/demultiplexer module based on a property of light that was not being exploited in communications systems: the optical vortex. [35] Optical chips are still some way behind electronic chips, but we're already seeing the results and this research could lead to a complete revolution in computer power. [34] Electronics could work faster if they could read and write data at terahertz frequency, rather than at a few gigahertz. [33] A team of researchers led by the Department of Energy's Oak Ridge National Laboratory has demonstrated a new method for splitting light beams into their frequency modes. [32]

As for possible applications, Hennrich says that the latest work might be used to improve error correction in quantum computers, given that weak measurements could in principle allow errors to be detected in quantum states without destroying those states in the process. [23] Physicists from MIPT have teamed up with their colleagues in Russia and Great Britain and developed a superconducting quantum state detector. The new device can detect magnetic fields at low temperatures and is useful to both researchers and quantum computer engineers. [22] ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product. [21] Cheng Chin, professor in the Department of Physics, and his team looked at an experimental setup of tens of thousands of atoms cooled down to near absolute zero. As the system crossed a quantum phase transition, they measured its behavior with an extremely sensitive imaging system. [20] Scientists from three UK universities are to test one of the fundamental laws of physics as part of a major Europe-wide project awarded more than £3m in funding. ]19] A team of researchers has devised a simple way to tune a hallmark quantum effect in graphene-the material formed from a single layer of carbon atoms-by bathing it in light. [18] Researchers from the University of Cambridge have taken a peek into the secretive domain of quantum mechanics. [17] Scientists at the University of Geneva (UNIGE), Switzerland, recently reengineered their data processing, demonstrating that 16 million atoms were entangled in a one-centimetre crystal. [15] The fact that it is possible to retrieve this lost information reveals new insight into the fundamental nature of quantum measurements, mainly by supporting the idea that quantum measurements contain both quantum and classical components.

Physicists at ETH Zurich have demonstrated a five-meter-long microwave quantum link, the longest of its kind to date. It can be used both for future quantum computer networks and for experiments in basic quantum physics research. [16] Our world has no dearth of complex networks-from cellular networks in biology to intricate web networks in technology. [15] Thanks to a new quantum approach, researchers in China have now found that proteins could fold much faster than previous calculations suggest. [14] What if the brain could detect its own disease? Researchers have been trying to create a material that "thinks" like the brain does, which would be more sensitive to early signs of neurological diseases such as Parkinson's. [13] University Professor of Applied Physics Stephen Arnold and his team at the New York University Tandon School of Engineering have made a discovery that could lead to Star Trek-like biosensor devices capable of flagging the barest presence in blood of a specific virus or antibody, or protein marker for a specific cancer; or sniffing out airborne chemical warfare agents while they are still far below toxic levels. [12] Lead researcher Dr Jonathan Breeze, from Imperial's Department of Materials, said: "This breakthrough paves the way for the widespread adoption of masers and opens the door for a wide array of applications that we are keen to explore. We hope the maser will now enjoy as much success as the laser." [11] Japanese researchers have optimized the design of laboratory-grown, synthetic diamonds. [10] Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology. A recent finding by Northwestern University's Prem Kumar adds further evidence that the answer might be yes. [9] A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. [8] This paper contains the review of quantum entanglement investigations in living systems, and in the quantum mechanically modeled photoactive prebiotic kernel systems. [7] The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

The new method also opens up new possibilities for quantum information processing, for example, by using phonons as a quantum memory. [25] A team of researchers at Stanford University has developed a theoretical way to cool down heated objects. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22] The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and Tel Aviv University were inspired by the seminal work of three British researchers who won the 2016 Noble Prize in Physics for their work, which teased out that particular properties of matter (such as electrical conductivity) can be preserved in certain materials despite continuous changes in the matter's form or shape. [21] Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18] Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. [17] Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations. [16]

Laser technology confines light inside a resonator containing a gain medium, a material with quantum properties that can amplify light. As laser resonators are generally far larger than the wavelength of light, lasing inside their cavities can occur in a wide range of patterns, which are known as modes. [16] In an article published in Applied Physics Letters Photonics this week, the researchers show that the light-sound interaction is particularly strong in diamond, and have demonstrated the first bench-top Brillouin laser that uses diamond. [15] Fully contact-free laser ultrasound (LUS) imaging has been demonstrated in humans by researchers at Massachusetts Institute of Technology (MIT), in collaboration with MIT Lincoln Laboratory. Xiang Zhang and colleagues used an infrared laser to generate sound waves at the tissue surface of volunteers' forearms. [14] Optical Mammography, or OM, which uses harmless red or infrared light, has been developed for use in conjunction with X-rays for diagnosis or monitoring in cases demanding repeated imaging where high amounts of ionizing radiation should be avoided. [13] University Professor of Applied Physics Stephen Arnold and his team at the New York University Tandon School of Engineering have made a discovery that could lead to Star Trek-like biosensor devices capable of flagging the barest presence in blood of a specific virus or antibody, or protein marker for a specific cancer; or sniffing out airborne chemical warfare agents while they are still far below toxic levels.

A superconductor can switch the magnetic moment of a single-molecule magnet placed on top of it. [28] Discovered more than 100 years ago, superconductivity continues to captivate scientists who seek to develop components for highly efficient energy transmission, ultrafast electronics or quantum bits for next-generation computation. [27] One of the greatest mysteries in condensed matter physics is the exact relationship between charge order and superconductivity in cuprate superconductors. [26] Cuprates hold the record high superconducting temperature at ambient pressure so far, but understanding their superconducting mechanism remains one of the great challenges of physical sciences listed as one of 125 quests announced by Science. [25] Now, scientists at Tokyo Institute of Technology (Tokyo Tech), the University of Tokyo and Tohoku University report curious multi-state transitions of these superconductors in which they change from superconductor to special metal and then to insulator. [24] Researchers at the Zavoisky Physical-Technical Institute and the Southern Scientific Center of RAS, in Russia, have recently fabricated quasi-2-D superconductors at the interface between a ferroelectric Ba0.8Sr0.2TiO3 film and an insulating parent compound of La2CuO4. [23] Scientists seeking to understand the mechanism underlying superconductivity in "stripe-ordered" cuprates-copper-oxide materials with alternating areas of electric charge and magnetism-discovered an unusual metallic state when attempting to turn superconductivity off. [22] This discovery makes it clear that in order to understand the mechanism behind the enigmatic high temperature superconductivity of the cuprates, this exotic PDW state needs to be taken into account, and therefore opens a new frontier in cuprate research. [21] High-temperature (Tc) superconductivity typically develops from antiferromagnetic insulators, and superconductivity and ferromagnetism are always mutually exclusive. [20]

US manufacturing and technology group Honeywell said Tuesday it will bring to market "the world's most powerful quantum computer" aimed at tackling complex scientific and business challenges. [35] New research gives insight into a recent experiment that was able to manipulate an unprecedented number of atoms through a quantum simulator. This new theory could provide another step on the path to creating the elusive quantum computers. [34] Chinese scientists Xianmin Jin and his colleagues from Shanghai Jiao Tong University have successfully fabricated the largest-scaled quantum chip and demonstrated the first two-dimensional quantum walks of single photons in real spatial space, which may provide a powerful platform to boost analog quantum computing for quantum supremacy. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [29] Magnetic materials that form helical structures-coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule-occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors-sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields.

Using energy quantization according to Planck and de Broglie wave-particle duality, the Einstein mass and energy equivalence formula is theoretically rigorously derived. The conclusion of this formula is also given on the basis of the concepts of classical physics and the principle of mass equivalence. It is shown that the equivalence of invariant and gravitational masses in the microworld manifests itself as the duality of the wave and particle, which expresses the equivalence of kinetic and potential energies. But, since the equivalence of the particle and wave properties of microparticles has long been proven experimentally, therefore, the principle of mass equivalence can be considered strictly proved.

In an article published in Applied Physics Letters Photonics this week, the researchers show that the light-sound interaction is particularly strong in diamond, and have demonstrated the first bench-top Brillouin laser that uses diamond. [15] Fully contact-free laser ultrasound (LUS) imaging has been demonstrated in humans by researchers at Massachusetts Institute of Technology (MIT), in collaboration with MIT Lincoln Laboratory. Xiang Zhang and colleagues used an infrared laser to generate sound waves at the tissue surface of volunteers' forearms. [14] Optical Mammography, or OM, which uses harmless red or infrared light, has been developed for use in conjunction with X-rays for diagnosis or monitoring in cases demanding repeated imaging where high amounts of ionizing radiation should be avoided. [13] University Professor of Applied Physics Stephen Arnold and his team at the New York University Tandon School of Engineering have made a discovery that could lead to Star Trek-like biosensor devices capable of flagging the barest presence in blood of a specific virus or antibody, or protein marker for a specific cancer; or sniffing out airborne chemical warfare agents while they are still far below toxic levels. [12] Lead researcher Dr Jonathan Breeze, from Imperial's Department of Materials, said: "This breakthrough paves the way for the widespread adoption of masers and opens the door for a wide array of applications that we are keen to explore. We hope the maser will now enjoy as much success as the laser." [11] Japanese researchers have optimized the design of laboratory-grown, synthetic diamonds. [10] Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology. A recent finding by Northwestern University's Prem Kumar adds further evidence that the answer might be yes. [9] A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. [8] This paper contains the review of quantum entanglement investigations in living systems, and in the quantum mechanically modeled photoactive prebiotic kernel systems. [7] The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

Significant advances in ultra-intense and ultra-short laser technology have led numerous laboratories to develop tabletop PW-class laser systems as a means of investigating laser-matter interactions in a relativistic regime.

With the rapid development of nanotechnology, devices like surface acoustic wave resonators and nanomechanical resonators are found to be suitable for generation, storage, and manipulation of few or even single phonon, which can be further applied in both classical and quantum information process. [32] In a recent report on Science, Yo Machida and a research team in the department of Physics and the Laboratory of Physics and Materials in Tokyo and France monitored the evolution of thermal conductivity in thin graphite. [31] Lattice thermal conductivity strongly affects the applications of materials related to thermal functionality, such as thermal management, thermal barrier coatings and thermoelectrics. [30] A team of researchers from the Helmholtz-Zentrum Berlin (HZB) and the University of Potsdam has investigated heat transport in a model system comprising nanometre-thin metallic and magnetic layers. [29] A new uncertainty relation, linking the precision with which temperature can be measured and quantum mechanics, has been discovered at the University of Exeter. [28] Physicists have demonstrated that energy quantization can improve the efficiency of a single-atom heat engine to exceed the performance of its classical counterpart. [27] A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators-resulting in leak-free machines that can stay operating longer. [26] Like watchmakers choosing superior materials to build a fine timepiece, physicists at the Centre for Quantum Technologies (CQT) at the National University of Singapore have singled out an atom that could allow them to build better atomic clocks. [25] Yale physicists have uncovered hints of a time crystal-a form of matter that "ticks" when exposed to an electromagnetic pulse-in the last place they expected: a crystal you might find in a child's toy. [24] The research shows that concentrated electrolytes in solution affect hydrogen bonding, ion interactions, and coordination geometries in currently unpredictable ways. [23]

A research collaboration led by the University of York's Department of Physics has created open-source software to assist in the creation of quantum materials which could in turn vastly increase the world's computing power. [25] A team of researchers at Stanford University has developed a theoretical way to cool down heated objects. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22] The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and Tel Aviv University were inspired by the seminal work of three British researchers who won the 2016 Noble Prize in Physics for their work, which teased out that particular properties of matter (such as electrical conductivity) can be preserved in certain materials despite continuous changes in the matter's form or shape. [21] Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18] Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. [17] Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations. [16]

Proof-of-principle experiments, such as the realisation of Nagaoka ferromagnetism, provide important guidance towards developing quantum computers and simulators of the future." [16] After all, it promises the discovery of new magnetic phenomena that may even be used for quantum computers in the future. [15] But for fast things like biomagnetic fields produced by firing neurons, we need to do better than that, or we might miss out on some information." [14] U.S. Army-funded researchers at Brandeis University have discovered a process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue. [13] Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. [12] UZH researchers have discovered a previously unknown way in which proteins interact with one another and cells organize themselves. [11] Dr Martin Sweatman from the University of Edinburgh's School of Engineering has discovered a simple physical principle that might explain how life started on Earth. [10] Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology.

A gyroscope sensitive enough to detect Earth's rotation has been created using a chip-based optical cavity. [33] Optical scintillation imaging is proving feasible as a quality assurance (QA) tool for small static beams and for pre-treatment verification of radiosurgery and volumetric-modulated arc therapy (VMAT) plans. [32] Tweaking the design of microring sensors enhances their sensitivity without adding more implementation complexity. [31] Large-scale plasmonic metasurfaces could find use in flat panel displays and other devices that can change colour thanks to recent work by researchers at the University of Cambridge in the UK. [30] Particles in solution can grow, transport, collide, interact, and aggregate into complex shapes and structures. [29] Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them. [28] Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

The device, which was developed by researchers at the University of Sussex in the UK, relies on a technique called nonlinear ghost imaging and could find applications in areas such as the life sciences, quality control in manufacturing and airport security.

Analysis of the simultaneous measurement stated in Heisenberg’s uncertainty principle reveals its root in special relativity theory. Hence a natural extension of this principle with general relativity is shown, where a small gravitational correction term needs to be introduced. This gravitational term being small remains negligible in ordinary conditions but becomes significant at small Planck scale. At Planck scale the modified uncertainty relation leads to natural calculation of Planck scale parameters used in quantum gravity theories. A careful consideration of the gravitational term showed its connection with cosmological dark energy and could explain the apparent large discrepancy between cosmological observed value and vacuum energy estimate from quantum field theory.

This paper offers some reflections on the theoretical distinction between the equally theoretical concepts of bosons and fermions, or spin-1 versus spin-1/2 particles. We do so by deconstructing Feynman’s Lecture on these distinctions. We apologize for the informal nature of the text, which basically reproduces a blog post of ours. We may or may not use more formal language in the next version of this paper.
