However, a team of researchers at MIT Lincoln Laboratory, together with Professor Juejun Hu and graduate students from MIT's Department of Materials Science and Engineering, is devising a way to control infrared light by using phase-change materials instead of moving parts. [50] A new method developed by Northwestern Engineering's Manijeh Razeghi has greatly reduced a type of image distortion caused by the presence of spectral cross-talk between dual-band long-wavelength photodetectors. [49] Plasmonic materials can uniquely control the electromagnetic spectrum due to nano-scale surface architecture. [48] A research group led by Yasuhiro Kuramitsu at Osaka University has revealed a magnetic reconnection driven by electron dynamics for the first time ever in laser-produced plasmas using the Gekko XII laser facility at the Institute of Laser Engineering, Osaka University. [47] By using this method for microscopic failure analysis, researchers and manufacturers could improve the reliability of the MEMS components that they are developing, ranging from miniature robots and drones to tiny forceps for eye surgery and sensors to detect trace amounts of toxic chemicals. [46] A KAIST team developed an optical technique to change the color (frequency) of light using a spatiotemporal boundary. [45] Researchers from the Structured Light group from the School of Physics at the University of the Witwatersrand in Johannesburg, South Africa, have found a way to use the full beam of a laser single cells in a human body, tiny particles in small volume chemistry, or working on future on-chip devices. [44] This research work by the UEx, which has been published in Scientific Reports, explored the electromagnetic properties of specific materials that can make certain objects invisible when they are introduced into its interior. [43] A research team from ITMO University and the Australian National University has discovered that different metasurfaces exhibit the same behavior provided a symmetry breaking is introduced to their unit cells "meta-atoms."[42]

Researchers in Austria have used lasers to levitate and cool a glass nanoparticle into the quantum regime. [25] With this control, researchers can integrate topology information into the photons, which can then be used as messengers for carrying quantum information. [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. [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 electron-proton scattering experiment by the PRad (proton radius) team at Jefferson Lab measured the root mean square (rms) charge radius of the proton as rp = 0.831 ± 0.007(stat) ± 0.012(syst) fm. We offer a theoretical explanation of the new measurement based on a ring current model of a proton.
This model further builds on older ring current and/or Zitterbewegung models for an electron and, hence, we will also highlight those results when relevant. We obtain a theoretical radius that is equal to four times the range parameter (ħ/mc) in Yukawa’s formula:
r = 4ħ/mc = 0.841 fm.
The 1/4 factor stems from the energy equipartition theorem: using Wheeler’s ‘mass without mass’ idea, we effectively assume half of the energy of a proton is explained by the electromagnetic, while the other half is attributed to the strong force, which we do not model but isolate from the analysis using the energy equipartition theorem. As for the small difference between the theoretical and measured radius, we attribute this to the mathematical idealizations that underpin ring current models. While useful and necessary as a concept, we think pointlike electric charges with zero rest mass and/or zero dimension that, therefore, move at light-speed, do not exist: they must have some (very) small dimension which explains the anomaly. We think mathematical idealization also explains the anomalous magnetic moment of an electron.
We think the calculations may offer a model of matter-particles in general.

Quantum computing, a fancy word resting on equally fancy fundamentals in quantum mechanics, has become a media hype, a mainstream topic in popular culture and an eye candy for high-tech company researchers and investors alike. Quantum computing has the power to provide faster, more efficient, secure and accurate computing solutions for emerging future innovations. Governments the world over, in collaboration with high-tech companies, pour in billions of dollars for the advancement of computing solutions quantum-based and for the development of fully functioning quantum computers that may one day aid in or even replace classical computers. Despite much hype and publicity, most people do not understand what quantum computing is, nor do they comprehend the significance of the developments required in this field, and the impact it may have on the future. Through this lecture notes, we embark on a pedagogic journey of understanding quantum computing, gradually revealing the concepts that form its basis, later diving in a vast pool of future possibilities that lie ahead, concluding with understanding and acknowledging some major hindrance and speed breaking bumpers in their path.

"We developed a new imaging method to better understand the transition from liquid to gas that occurs before fuel combustion," said research team leader Edouard Berrocal from the Division of Combustion Physics, Department of Physics at Lund University in Sweden. [16] Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays. [15] In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents. [14] The interaction of high-power laser light sources with matter has given rise to numerous applications including; fast ion acceleration; intense X-ray, gamma-ray, positron and neutron generation; and fast-ignition-based laser fusion.

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have for the first time created and imaged a novel pair of quantum dots-tiny islands of confined electric charge that act like interacting artificial atoms. [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]

Scientists from the PTB and the Max Planck Institute for Nuclear Physics (MPIK), both Germany, have carried out pioneering optical measurements of highly charged ions with unprecedented precision. [41] Scientists from Argonne National Laboratory and the University of Chicago launched a new testbed for quantum communication experiments from Argonne last week. [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] 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. [32]

Qubits Precisely Controlled by Technology Of the many divergent approaches to building a practical quantum computer, one of the most promising paths leads toward ion traps. [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.

This year’s Photonics West and BIOS events will bring together scientists, entrepreneurs and big business to discuss the trends that will drive the future of the optics industry. [36] Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a simple yet accurate method for finding defects in the latest generation of silicon carbide transistors. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [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.

This study describes the significance of a 0-sphere on the behavior of electrons. The 0-sphere is suitable for representing the positions of the two bare electrons which mentioned in the previous study. It was a model that two bare electrons emit the thermal potential energy on one side and absorb the energy in another side. An electron travels by cyclically repeating both of the radiation and absorption. The position coordinates of these two bare electrons could be represented by the 0-sphere.

A team of physicists has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. [24] Magnetoresistance-a variation of electrical resistance in response to an externally applied magnetic field-is important for all magnetic field sensor applications. [23] As a result of climate change, population growth, and rising expectations regarding quality of life, energy requirements for cooling processes are growing much faster worldwide than for heating. [22] Researchers at The Ohio State University have discovered how to control heat with a magnetic field. [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] 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]

"Think what we can do if we teach a quantum computer to do statistical mechanics," posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy's Brookhaven National Laboratory. [37] Among many important and fundamental issues in science, solving the Schroedinger equation (SE) of atoms and molecules is one of the ultimate goals in chemistry, physics and their related fields. [36] The standard approach to building a quantum computer with majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing-quantum chemistry-would require these qubits to be converted again into so-called fermions. [35] Scientists have shown how an optical chip can simulate the motion of atoms within molecules at the quantum level, which could lead to better ways of creating chemicals for use as pharmaceuticals. [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.

The effect of rapid rotation on a single quantum spin in a piece of diamond has been measured for the first time. Alexander Wood of the University of Melbourne and colleagues rotated the diamond at 200,000 rpm and used laser light and microwaves to measure the effect on the spin. [36] A new method to read out the spin states of individual negatively-charged nitrogen vacancy (NV-) centres has been developed by researchers in Europe and Japan. [35] Now, teams from France, Spain and Germany have demonstrated the feasibility of another approach at the nanoscale: "We can induce magnetic order on a small region of our sample by employing a small electric field instead of using magnetic fields," Dr. Sergio Valencia, HZB, says. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion.

New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical fiber networks. [41] Their research involved exploring how to exploit multicore fiber-optic technology that is expected to be used in future transmission networks. [40] When Greg Bowman presents a slideshow about the proteins he studies, their 3-D shapes and folding patterns play out as animations on a big screen. [39] Researchers at the University of Helsinki uncovered the mechanisms for a novel cellular stress response arising from the toxicity of newly synthesized proteins. [38] Scientists have long sought to develop drug therapies that can more precisely diagnose, target and effectively treat life-threatening illness such as cancer, cardiovascular and autoimmune diseases. [37] Skin cells taken from patients with a rare genetic disorder are up to ten times more sensitive to damage from ultraviolet A (AVA) radiation in laboratory tests, than those from a healthy population, according to new research from the University of Bath. [36] The use of stem cells to repair organs is one of the foremost goals of modern regenerative medicine. [35] Using new technology to reveal the 3-D organization of DNA in maturing male reproductive cells, scientists revealed a crucial period in development that helps explain how fathers pass on genetic information to future generations.

Currently, natural philosophy (Physics) lacks the most fundamental model and a complete set of self-consistent explanations. This article attempts to address several issues to fill in the gaps. Starting from the most basic philosophical paradoxes, I deduce a physical model (the natural philosophical outlook) to describe the laws governing the operation of the universe. Based on this model, a mathematical model is established to describe the generalized diffusion behavior of a moving particle swarm, for which the form without external field is simply verified. In this article, the gravitational force and relativistic effects are interpreted for the first time as a statistical effect of randomly moving particles. Thus, the gravitational force and special relativistic effects are integrated into a single equation (achieved by selecting an initial wave function with a specific norm when solving it), and the cause of stable particle formation is also revealed. The derived equation and the method of acquiring the initial wave function are fully self-consistent with the hypotheses stated in the physical model, thereby also proving the reliability of the physical model to some extent. Some of these ideas may have potential value as a basis for understanding the essence of quantum mechanics, relativity and superstring theory, as well as for gaining a further understanding of nature and the manufacture of quantum computers.

Physicists at LMU, together with colleagues at Saarland University, have successfully demonstrated the transport of an entangled state between an atom and a photon via an optic fiber over a distance of up to 20 km-thus setting a new record. [34] A scientist involved in expanding quantum communication to a network of users, is continuing his work at the University of Bristol. [33] In recent years, nanofabricated mechanical oscillators have emerged as a promising platform for quantum information applications. [32] Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution".

In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference.

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] 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]

The electron-proton scattering experiment by the PRad (proton radius) team at Jefferson Lab measured the root mean square (rms) charge radius of the proton as rp = 0.831 ± 0.007(stat) ± 0.012(syst) fm.
Assuming all of the electric charge in the proton is packed into a single pointlike (elementary) charge and applying the ring current model to a proton, one gets a radius for the circular current that is equal to a = 2μ/qc = 0.58736 fm. Using CODATA values for all variables and constants in this equation, and applying a √2 form factor to, somehow, account for the envelope of the magnetic field around the ring current, yields an electric charge radius of 0.8065 fm. The difference between the PRad point estimate and this theoretical value is 0.00035 fm, which represents 5% of the standard error (0.007 fm) of PRad’s point estimate. It is, therefore, hard to argue this is a mere coincidence.
We can also calculate a proton radius based on the idea of a strong charge. This radius corresponds to the range parameter in Yukawa’s equation and is equal to a = ħ/mpc = 0.2103, which is about 1/4 of the PRad point estimate. This 1/4 factor is, obviously, far more mysterious, and the difference between 0.831 and this strong charge radius multiplied by 4 is 0.01 fm, which is about 50% of the combined statistical and systematic error (0.007 + 0.012 = 0.019). We, therefore, think that, while being somewhat less precise, the 1/4 factor cannot be a coincidence.
We, therefore, feel the new measurement of the proton radius by JLAB’s PRad team may lend credibility to attempts to extend the Zitterbewegung hypothesis from electrons to also include protons and other elementary particles. In contrast, the measurement is hard to fit into a model of oscillating quarks that have partial charge only.

Applying bound states in the continuum (BICs) in photonic integrated circuits enables low-loss light guidance and routing in low-refractive-index waveguides on high-refractive-index substrates. [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.

A new technique to study the properties of molecules and materials on a quantum simulator has been discovered. [44] Quantum simulation plays an irreplaceable role in diverse fields, beyond the scope of classical computers. [43] In a cooperative project, theorists from the the Max Planck Institute of Quantum Optics in Garching anf the Consejo Superior de Investigaciones Científicas (CSIC) have now developed a new toolbox for quantum simulators and published it in Science Advances.

Recently, physicists have observed that the two families of known high-temperature superconductors-copper-and iron-based compounds-both exhibit a unique phenomenon in which electronic degrees of freedom can break the overall crystal rotational symmetry and form what is known as the electronic nematic phase. [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. [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.

Laboratory have developed a new method to measure how photocurrents flow in a 2-D material-a result that could have implications for developing quantum sensors and next-generation electronics. [38] NIMS and Hokkaido University jointly discovered that proton transfer in electrochemical reactions is governed by the quantum tunneling effect (QTE) under the specific conditions. [37] Researchers at the University of Vienna study the relevance of quantum reference frames for the symmetries of the world. [36] Researchers in Singapore have built a refrigerator that's just three atoms big. This quantum fridge won't keep your drinks cold, but it's cool proof of physics operating at the smallest scales. [35] Researchers have created a new testing ground for quantum systems in which they can literally turn certain particle interactions on and off, potentially paving the way for advances in spintronics. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [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]

An international team of researchers from ITMO University, the Australian National University, and Korea University have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator a few hundred nanometers in size for a record-breaking time. [33] An international research team has found a way to make light frequency conversion at the nanoscale 100 times more efficient. [32] The precision of measuring nanoscopic structures could be substantially improved, thanks to research involving the University of Warwick and QuantIC researchers at the University of Glasgow and Heriot Watt University into optical sensing. [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. [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]

This paper complements an earlier (Nov 2018) paper on the metaphysics of physics. The earlier paper focused on an alternative (realist) interpretation of quantum mechanics. While inspired by the previous one, this follow-up paper is a much simpler one: we just offer very basic thoughts on the most fundamental physical concepts, which are the idea of force, energy and mass.
Based on the recent precision measurements of the (electric) charge radius of a proton, we also argue previous reflections on the zbw radius of a proton make more sense now.
Needless to say, we also offer our usual reflections on the concept of fields and messenger particles. We think the first is very useful – even if fields are relative. In contrast, we argue that the latter (the idea of virtual photons, gluons or other messenger particles) is purely metaphysical. In other words, we continue to think the idea of messenger particles is a non-scientific successor to aether theories.

Northwestern University researchers have added a new dimension to the importance of diversity. For the first time, physicists have experimentally demonstrated that certain systems with interacting entities can synchronize only if the entities within the system are different from one another. [29] It may seem surprising, but theories and formulas derived from physics turn out to be useful tools for understanding the ways democratic elections work, including how these systems break down and how they could be improved. [28] Electrons whizzing around each other and humans crammed together at a political rally don't seem to have much in common, but researchers at Cornell are connecting the dots. [27] Now a group of actual physicists from Australia and Switzerland have proposed a device which uses the quantum tunneling of magnetic flux around a capacitor, breaking time-reversal symmetry. [26] The arrow of time and the accelerated expansion are two fundamental empirical facts of the universe. [25] The intensive, worldwide search for dark matter, the missing mass in the universe, has so far failed to find an abundance of dark, massive stars or scads of strange new weakly interacting particles, but a new candidate is slowly gaining followers and observational support. [24] "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]

Photoelectric effect and the production of X-Rays in Cathode Ray Tube are two correlated phenomena. It is quite surprising to note that there has been no substantial attention given to this correlation. It is possible to bridge these two separate processes, enabling us to study the quantum interactions which occur naturally. A modified version of Photoelectric setup can be used, in which the ejected photoelectrons with high energies travel to the anode. A heavy metal viz. Tungsten is used as anode, which produces X-Rays due to photoelectronic collisions with anode. The photoelectrons are assumed to be non-relativistic and a relation is obtained between the De-Broglie Wavelength of the photoelectrons (λ_e) and the wavelength of X-Rays (λ_x) such that λ_x=Ψ〖λ_e〗^2.
The connection of results with a possible proof of De-Broglie Bohm Hypothesis is then discussed in Final Discussion.

[44] A team of researchers is using ultrasonic nondestructive testing (NDT) that involves amplifying the signal from a photoacoustic laser source using laser-absorbing patch made from an array of nanoparticles from candle soot and polydimethylsiloxane. [43] An explosion is a complex event involving quickly changing temperatures, pressures and chemical concentrations. [42] A team led by University of Utah physicists has discovered how to fix a major problem that occurs in lasers made from a new type of material called quantum dots. [41] A team of researchers from the University of Central Florida and Michigan Technological University has developed a laser system concept built on the principles of supersymmetry. [40] Laser physicists have succeeded in reducing the acquisition time for data required for reliable characterization of multidimensional electron motions by a factor of 1000. [39] Princeton researchers have demonstrated a new way of making controllable "quantum wires" in the presence of a magnetic field, according to a new study published in Nature. [38] Physicists at the Kastler Brossel Laboratory in Paris have reached a milestone in the combination of cold atoms and nanophotonics. [37] The universal laws governing the dynamics of interacting quantum particles are yet to be fully revealed to the scientific community. [36] Now NIST scientists have designed a vacuum gauge that is small enough to deploy in commonly used vacuum chambers. [35]

This paper adds some thoughts on relativity theory and geometry to our one-cycle photon model. We basically highlight what we should think of as being relative in this model (energy, wavelength, and the related force/field values), as opposed to what is absolute (the geometry of spacetime and the geometry of the photon). We also expand our photon model somewhat by introducing an electromagnetic vector combining electric and magnetic fields. Finally, we add a discussion on how we can think about photon-electron interactions and polarization.

The world's first thought power meter is present. Its first result is that thought force with no electric field is able to change the current and voltage in an electric circuit . This result has conclusions. The most important is the following one: there is only one fundamental interaction, because every known interaction can be explained by one ultimate fundamental interaction called Force I of All. (Pronunciation: “Force the First”.) Force I is the interaction between space and matter. Thought force is one existing form of Force I and though force measured is the first evidence that Force I exists.

In a new study, U.S. and Austrian physicists have observed quantum entanglement among "billions of billions" of flowing electrons in a quantum critical material. [36] Researchers at Technische Universität Darmstadt have recently demonstrated the defect-free assembly of versatile target patterns of up to 111 single-atom quantum systems. [35] Physicists at the National Institute of Standards and Technology (NIST) have teleported a computer circuit instruction known as a quantum logic operation between two separated ions (electrically charged atoms), showcasing how quantum computer programs could carry out tasks in future large-scale quantum networks. [34] Scientists have developed a topological photonic chip to process quantum information, promising a more robust option for scalable quantum computers. [33] With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. [32] A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface. [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [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] A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference.

Experimental physicists have combined several measurements of quantum materials into one in their ongoing quest to learn more about manipulating and controlling the behavior of them for possible applications. [30] These emerging magnetic properties suggest that the dots could, indeed, have potential in quantum computing as storage and processing devices. [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.

One of the open questions in quantum research is how heat and thermodynamics coexist with quantum physics. [39] But one lesser-known field is also starting to reap the benefits of the quantum realm-medicine. [38] A quantum squeezing and amplification technique has been used to measure the position of a trapped ion to subatomic precision. [37] A new theoretical model involves squeezing light to just the right amount to accurately transmit information using subatomic particles. [36] The standard approach to building a quantum computer with majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing-quantum chemistry-would require these qubits to be converted again into so-called fermions. [35] Scientists have shown how an optical chip can simulate the motion of atoms within molecules at the quantum level, which could lead to better ways of creating chemicals for use as pharmaceuticals. [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]

As researchers develop clever approaches to achieve that goal, this subject alone could be a theme of another exciting symposium." [41] A team at Osaka University has created single-molecule nanowires, complete with an insulation layer, up to 10 nanometers in length. [40] Using optical and electrical measurements, a two-dimensional anisotropic crystal of rhenium disulfide was found to show opposite piezoresistant effects along two principle axes, i.e. positive along one axis and negative along another. [39] A team of researchers from the University of Konstanz has demonstrated a new aqueous polymerization procedure for generating polymer nanoparticles with a single chain and uniform shape, which, by contrast to previous methods, involves high particle concentrations. [38] A team of researchers from China, the U.S. and Japan has developed a way to strengthen graphene-based membranes intended for use in desalination projects-by fortifying them with nanotubes. [37] The team arrived at their results by imaging gold nanoparticles, with diameters ranging from 2 to 5 nanometres, via aberration corrected scanning transmission electron microscope. [36] Nanoparticles of less than 100 nanometres in size are used to engineer new materials and nanotechnologies across a variety of sectors. [35] For years, researchers have been trying to find ways to grow an optimal nanowire, using crystals with perfectly aligned layers all along the wire. [34] Ferroelectric materials have a spontaneous dipole moment which can point up or down. [33] Researchers have successfully demonstrated that hypothetical particles that were proposed by Franz Preisach in 1935 actually exist. [32] Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, and then back again, with single flashes of laser light.

[32] A potential revolution in device engineering could be underway, thanks to the discovery of functional electronic interfaces in quantum materials that can self-assemble spontaneously. [31] Now, for the first time ever, researchers from Aalto University, Brazilian Center for Research in Physics (CBPF), Technical University of Braunschweig and Nagoya University have produced the superconductor-like quantum spin liquid predicted by Anderson. [30] Electrons in graphene-an atomically thin, flexible and incredibly strong substance that has captured the imagination of materials scientists and physicists alike-move at the speed of light, and behave like they have no mass. [29] In a series of exciting experiments, Cambridge researchers experienced weightlessness testing graphene's application in space. [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.

Basic physical fields are dynamic fields like our universe and the fields that are raised by electric charges. These fields are dynamic continuums. Most physical theories treat these fields by applying gravitational theories or by Maxwell equations. Mathematically these fields can be represented by quaternionic fields. Dedicated normal operators in quaternionic non-separable Hilbert spaces can represent these quaternionic fields in their continuum eigenspaces. Quaternionic functions can describe these fields. Quaternionic differential and integral calculus can describe the behavior of these fields and the interaction of these fields with countable sets of quaternions. All quaternionic fields obey the same quaternionic differential equations. The basic fields differ in their start and boundary conditions.
The paper introduces the concept of the Hilbert repository. It is part of a hierarchy of structures that mark increasingly complicated realizations of a purely mathematical model that describes and explains most features of observable physical reality. That model is the Hilbert Book Model.
The paper treats the mathematical and experimental underpinning of the Hilbert Book Model.

The chess world was amazed when the computer algorithm AlphaZero learned, after just four hours on its own, to beat the best chess programs built on human expertise. Now a research group at Aarhus University in Denmark has used the very same algorithm to control a quantum computer. [39] Researchers have discovered that input-output maps, which are widely used throughout science and engineering to model systems ranging from physics to finance, are strongly biased toward producing simple outputs. [38] A QEG team has provided unprecedented visibility into the spread of information in large quantum mechanical systems, via a novel measurement methodology and metric described in a new article in Physics Review Letters. [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]

Einstein mass–energy equivalence equation E=mc^2 is wrong because does not contains Dark Matter
Einstein in 1905 did not formulate exactly the equation E=mc^2 but he said: ’if a body gives off the energy L in the form of radiation, its mass diminishes by L/c^2’. Thus means for Einstein the inertial mass of an object changes if the object absorbs or emits energy.

Los Alamos scientists have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes (LEDs) containing an integrated optical resonator, which allows them to function as lasers.

Transistors based on germanium can perform calculations for future quantum computers. This discovery by the team of Menno Veldhorst is reported in Nature. [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] A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India. [26] Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal. [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.

Scientists from Argonne National Laboratory and the University of Chicago launched a new testbed for quantum communication experiments from Argonne last week. [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] 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. [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.

In the quantum realm, under some circumstances and with the right interference patterns, light can pass through opaque media. [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.

With enhanced properties such as greater strength, lighter weight, increased electrical conductivity and chemical reactivity, nanomaterials (NMs) are widely used in areas like ICT, energy and medicine. [35] Scientists at the Okinawa Institute of Science and Technology Graduate University (OIST) have developed a light-based device that can act as a biosensor, detecting biological substances in materials; for example, harmful pathogens in food samples. [34] A tightly focused, circularly polarized spatially phase-modulated beam of light formed an optical ring trap. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [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]

Physicists at ETH Zurich have observed a surprising twist in a quantum system caused by the interplay between energy dissipation and coherent quantum dynamics. [35] Cloning of quantum states is used for eavesdropping in quantum cryptography. [34] Researchers at the Center for Quantum Nanoscience within the Institute for Basic Science (IBS) have made a major breakthrough in controlling the quantum properties of single atoms. [33] A team of researchers from several institutions in Japan has described a physical system that can be described as existing above "absolute hot" and also below absolute zero. [32] A silicon-based quantum computing device could be closer than ever due to a new experimental device that demonstrates the potential to use light as a messenger to connect quantum bits of information-known as qubits-that are not immediately adjacent to each other.

In order to reduce error rates even further and provide reliable operations much faster, researchers at Leibniz University Hannover and Physikalisch-Technische Bundesanstalt (PTB) have now developed a new method. [45] Scientists with the Institute for Molecular Engineering at the University of Chicago have made two breakthroughs in the quest to develop quantum technology. [44] A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz. [43] As the number of hacks and security breaches rapidly climbs, scientists say there may be a way to make a truly unhackable network by using the laws of quantum physics. [42] This world-first nanophotonic device, just unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' light. [41] Purdue University researchers created a new technique that would increase the secret bit rate 100-fold, to over 35 million photons per second. [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.

Neutrons are the particles that move on circular orbits inside the nuclei (with the remaining half of their kinetic energy) around immobilized protons which have spin only. If protons were rotating they would cause orbital magnetism, which has never been observed, beyond magnetic dipole moment of nucleons spin. In addition, no regression of proton has occurred, because it would cause alternating magnetism, which has also never been observed. The first nuclear units are the deuterium, the
tritium, the helium-3 and the helium-4, which is the basic structure unit of the large nuclei. The spin, the magnetic moment and the mass deficit of the above units and of the bonding neutrons are the three experimental constants upon which the nuclei structure is based.

Researchers at the University of Chicago and Argonne National Laboratory significantly reduced this gap by using data compression techniques to fit a 61-qubit simulation of Grover's quantum search algorithm on a large supercomputer with 0.4 percent error. [57] Quantum computation represents a fundamental shift that is now under way. What is most exciting is not what we can do with with a quantum computer today, but the undiscovered truths it will reveal tomorrow. [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 quantum anomalous Hall (QAH) effect can combine topology and magnetism to produce precisely quantized Hall resistance at zero magnetic field (an environment carefully screened from magnetic fields). [12] Using ultracold atoms trapped in a periodically modulated two-dimensional superlattice potential, the scientists could observe a dynamical version of a novel type of quantum Hall effect that is predicted to occur in four-dimensional systems. [11] Using two types of "designer" quantum dots, researchers are creating double-pane solar windows that generate electricity with greater efficiency and create shading and insulation for good measure. [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.

A team headed by Professor Frank Stienkemeier at Freiburg's Institute of Physics and Dr. Marcel Mudrich, professor at the University of Aarhus in Denmark, has observed the ultrafast reaction of nanodroplets of helium after excitation with extreme ultraviolet radiation (XUV) using a free-electron laser in real time. [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.

Researchers at SAGA Light Source, the University of Toyama, Hiroshima University and the Institute for Molecular Science have demonstrated a method to control the shape and orientation of an electron cloud in an atom by tuning the attosecond spacing in a double pulse of synchrotron radiation. [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] 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]

[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.

Physicists have shown that the motion of domain walls can be detected by monitoring voltage generated in superconducting devices. [38] Northeastern researchers have used a powerful computer model to probe a puzzling class of copper-based materials that can be turned into superconductors. [37] A NIMS-Ehime University joint research team succeeded in discovering new materials that exhibit superconductivity under high pressure using materials informatics (MI) approaches (data science-based material search techniques). [36] Measuring the properties of superconducting materials in magnetic fields at close to absolute zero temperatures is difficult, but necessary to understand their quantum properties. [35] Scientists from Russia, China and the United States predicted and have now experimentally identified new uranium hydrides, predicting superconductivity for some of them. [34] Russian physicists from MIPT teamed up with foreign colleagues for a groundbreaking experimental study of a material that possesses both superconducting and ferromagnetic properties. [33] An international group of scientists, including a researcher from Skoltech, has completed an experimental and theoretical study into the properties displayed by strongly disordered superconductors at very low temperatures. [32] The researchers found that via quick-freeze technique, the metal changed into a superconducting state for over a week. [31] Scientists of the University of Twente and the University of Amsterdam now demonstrate a new property: the non-superconducting material bismuth shows lossless current conduction. [30] A team of international scientists including Maia G. Vergniory, Ikerbasque researcher at DIPC and UPV/EHU associate, has discovered a new class of materials, higher-order topological insulators. [29] A team of researchers from Japan, the U.S. and China, has identified a topological superconducting phase for possible use in an iron-based material in quantum computers. [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.

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.

Classical physics is characterized by the precision of its equations describing the evolution of the world as determined by the initial conditions of the Big Bang—meaning there is no room for chance. [34]
There was a period in the very early universe—known as the "cosmic dark ages"—when elementary particles, formed in the Big Bang, had combined to form neutral hydrogen but no stars or galaxies existed yet to light up the universe. [33]
New observations and analysis made by a team of astronomers at Yonsei University (Seoul, South Korea), together with their collaborators at Lyon University and KASI, show, however, that this key assumption is most likely in error. [32]

We propose quantum cryptography based on
an algorithm of determining a function.
The security of our cryptography is based on the Ekert 1991 protocol, that is,
we use an entangled state.
Eve must destroy the entangled state.
Consider a function.
Alice knows all the mappings concerning
the function.
Bob knows none of them.
His aim is of obtaining all of them without Eve's attack.
In classical case, Bob needs some queries.
In quantum case, Bob needs just a query.
By measuring the
single entangled state, which is sent by Alice, Bob can obtain
all the mappings concerning
the function, simultaneously.
This is faster than classical cryptography.

"When the Italian physicist Ettore Majorana predicted the possibility of a new fundamental particle which is its own antiparticle, little could he have envisioned the long-lasting implications of his imaginative idea," said Nitin Samarth, Downsbrough Department Head and professor of physics at Penn State. [34] As mysterious as the Italian scientist for which it is named, the Majorana particle is one of the most compelling quests in physics. [33] With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. [32] A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface. [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [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] A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference. [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]

Researchers at Columbia University and University of California, San Diego, have introduced a novel "multi-messenger" approach to quantum physics that signifies a technological leap in how scientists can explore quantum materials. [39] This inherent flexibility should enable many interesting applications in, for instance, computation and health care. [38] New research from Washington University in St. Louis and Argonne National Laboratory coaxes electrons down the track that they typically don't travel-advancing understanding of the earliest light-driven events of photosynthesis. [37] UK researchers have developed world-leading Compound Semiconductor (CS) technology that can drive future high-speed data communications. [36] "Regarding new perspectives, this could lead to similar fantastic developments as in the field of magnetism, such as electronic coherence in quantum computing," says Schultze hopefully, who now leads a working group focusing on attosecond physics A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface.

Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a quantum chemistry simulation benchmark to evaluate the performance of quantum devices and guide the development of applications for future quantum computers. [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.
