Ultrafast, multidimensional spectroscopy unlocks macroscopic-scale effects of quantum electronic correlations. [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.

Researchers at Aalto University and the University of Jyväskylä showed that graphene can be a superconductor at a much higher temperature than expected, due to a subtle quantum mechanics effect of graphene's electrons. [30] Hong Ding's group from the Institute of Physics, Chinese Academy of Science reported the superconducting gap of topological surface state is larger than that of bulk states in β-Bi2Pd thin films using in-situ angle-resolved photoemission spectroscopy and molecular beam epitaxy. [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.

Electrically-driven BIC microlasers with ultrafast switching are also possible and the cascade-wise on-chip integration of such ultrafast switchable BIC lasers is also essential for optical and quantum computing. This research is published in Science on Feb. 28, 2020. [17]

Researchers at the Paul Scherrer Institute PSI have measured a property of the neutron more precisely than ever before. [35] This event is considered as a striking proof of the existence of Majorana particles, and it represents a crucial step towards their use as building blocks for the development of quantum computers. [34] In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of superconductor. [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]

To help with this, researchers at Eindhoven University of Technology have developed a new mathematical tool to better explore how light propagates through optical fibers in this high power, or nonlinear, regime. [52] The nonlinear characteristics of metamaterials have displayed emerging potentials for frequency conversions owing to the induced local fields around the resonators. [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. [47] A team of scientists from Arizona State University's School of Molecular Sciences and Germany have published in Science Advances online today an explanation of how a particular phase-change memory (PCM) material can work one thousand times faster than current flash computer memory, while being significantly more durable with respect to the number of daily read-writes. [46] A new two-qubit quantum processor that is fully programmable and single electron spins that can be coherently coupled to individual microwave-frequency photons are two of the latest advances in the world of solid-state spin-based quantum computing. [45] Scientists at the National Institute of Standards and Technology (NIST) have now developed a highly efficient converter that enlarges the diameter of a HYPERLINK "https://phys.org/tags/light/" light beam by 400 times.

Furthermore, the directionality of such the chiral microlaser is all-optically and dynamically controlled by the bias in the pump direction, and the symmetry breaking threshold is adjustable using a nanotip scatterer. [37] "We put the optical microscope under a microscope to achieve accuracy near the atomic scale," said NIST's Samuel Stavis, who served as the project leader for these efforts. [36] Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. [35] A technique to manipulate electrons with light could bring quantum computing up to room temperature. [34] The USTC Microcavity Research Group in the Key Laboratory of Quantum Information has perfected a 4-port, all-optically controlled non-reciprocal multifunctional photonic device based on a magnetic-field-free optomechanical resonator. [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.

The appearance of a particle in a certain point in space, the full waves and the empty waves are considered as a consequence of subquantum processes. The experiment is described that measured the absorption of single photons by absorbers with various absorption coefficients, in one of the beams, after the photons interacted with the beam splitter. The measurements showed that the absorption corresponds to single photon traveling in either one or another beam. The results of our measurements and of single photon interference experiments, combined together, demonstrate the existence of the empty waves, that is, the excitations in the subquantum world, which do not contain a photon. We show that seemingly justified criticism of our interpretation of the experiment is not valid. New experiments are proposed to study single-photon interference involving an empty wave.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo report the first occurrence of directly splitting one photon into three. [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.

A novel "decentralized" protocol makes it possible to share secret information among multiple senders and receivers using quantum teleportation. [37] The CAS key lab of quantum information, led by Prof. Guo Guangcan, Li Chuanfeng, Xiang Guoyong and collaborators, reports enhancing the performance of quantum orienteering with entangling measurements via photonic quantum walks. [36] Researchers at Rensselaer Polytechnic Institute have come up with a way to manipulate tungsten diselenide (WSe2)-a promising two-dimensional material-to further unlock its potential to enable faster, more efficient computing, and even quantum information processing and storage. [35] The human brain has amazing capabilities making it in many ways more powerful than the world's most advanced computers. [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.

Some molecules, including most of the ones in living organisms, have shapes that can exist in two different mirror-image versions. [21] "This research opens an exciting new direction for camera technology with unprecedented compactness, allowing us to envision applications in atmospheric science, remote sensing, facial recognition, machine vision and more," said Capasso. [20] A compact and simple camera that can determine the full polarization of light has been developed by researchers in the US. [19] In their experiments, the researchers first transformed an ordinary laser beam into an accelerating one by reflecting the laser beam off of a spatial light modulator. [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.

Researchers have been conducting laser cooling experiments on atoms and ions for decades now. So far, however, no study had observed mixtures of both atoms and ions at extremely low temperatures. [25] University of Adelaide researchers have delved into the realm of Star Wars and created a powerful tractor beam-or light-driven energy trap-for atoms. [24] The Purcell effect also has another advantage: It shortens the time it takes the rubidium atom to store and release the quantum information. [23] Monika Aidelsburger uses a special type of optical lattice to simulate quantum many-body phenomena that are otherwise inaccessible to experimental exploration. [22] University of Illinois Professor Harry Hilton brought together several mathematical and physical theories to help look at problems in more unified ways and solve physical engineering problems. [21] A team of physicists from RUDN, JINR (Dubna), and the University of Hamburg (Germany) developed a mathematical model for describing physical processes in hybrid systems that consists of atoms and ions cooled down to temperatures close to absolute zero. [20] Recently, extensive study shows that the parity-time symmetry breaking in open systems leads to exceptional points, promising for novel applications leasers and sensing. [19] A recent discovery by William & Mary and University of Michigan researchers transforms our understanding of one of the most important laws of modern physics. [18] Now, a team of physicists from The University of Queensland and the NÉEL Institute has shown that, as far as quantum physics is concerned, the chicken and the egg can both come first. [17]

In 1923, Arthur Holly Compton introduced what today is known as the Compton wave. Even if the Compton scattering derivation by Compton is relativistic in the sense that it takes into account the momentum of photons traveling at the speed of light, the original Compton derivation indirectly assumes that the electron is stationary at the moment it is scattered by electrons, but not after it has been hit by photons. Here, we extend this to derive Compton scattering for the case when the electron is initially moving at a velocity v. This gives us a relativistic Compton wave, something we remarkably have not seen published before.

Measuring a quantum system causes it to change-one of the strange but fundamental aspects of quantum mechanics. Researchers at Stockholm University have now been able to demonstrate how this change happens. [26] Researchers at the University of Florence and Istituto dei Sistemi Complessi, in Italy, have recently proved that the invasiveness of quantum measurements might not always be detrimental. [25] Now, researchers in the UK and Israel have created miniscule engines within a block of synthetic diamond, and have shown that electronic superposition can boost their power beyond that of classical devices. [24] In the latest wrinkle to be discovered in cubic boron arsenide, the unusual material contradicts the traditional rules that govern heat conduction, according to a new report by Boston College researchers in today's edition of the journal Nature Communications. [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. [22] "We studied two systems: a Bose-Einstein condensate with 100,000 atoms confined in a cavity and an optomechanical cavity that confines light between two mirrors," Gabriel Teixeira Landi, a professor at the University of São Paulo's Physics Institute (IF-USP), told. [21] Search engine entropy is thus important not only for the efficiency of search engines and those using them to find relevant information as well as to the success of the companies and other bodies running such systems, but also to those who run websites hoping to be found and visited following a search. [20] "We've experimentally confirmed the connection between information in the classical case and the quantum case," Murch said, "and we're seeing this new effect of information loss." [19]

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] 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.

Stevens imaging system will help researchers create crisp, highly detailed images of the human retina using almost invisibly faint laser beams that won't damage the eye's sensitive tissues. [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] 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]

After two years of research, and thanks to a sabbatical, University of Dayton researchers Andy Chong and Qiwen Zhan became the first to create a new "state of light"-showing it also can rotate around a transverse axis perpendicular to the direction light travels, like a cyclone.

[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]

Dark-field microscopy can reveal intricate details of translucent cells and aquatic organisms, as well as faceted diamonds and other precious stones that would otherwise appear very faint or even invisible under a typical bright-field microscope. [38] Using a familiar tool in a way it was never intended to be used opens up a whole new method to explore materials, report UConn researchers in Proceedings of the National Academy of Science. [37] "We put the optical microscope under a microscope to achieve accuracy near the atomic scale," said NIST's Samuel Stavis, who served as the project leader for these efforts. [36] Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. [35] A technique to manipulate electrons with light could bring quantum computing up to room temperature. [34] The USTC Microcavity Research Group in the Key Laboratory of Quantum Information has perfected a 4-port, all-optically controlled non-reciprocal multifunctional photonic device based on a magnetic-field-free optomechanical resonator. [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.

Recently, a research team from Shanghai Institute of Optics and Fine Mechanics, Chinese Academic of Sciences, has succeeded in developing a new kind of low-phonon-energy laser crystal. [38] A new laser-pointing platform developed at MIT may help launch miniature satellites into the high-rate data game. [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. [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]

In new results presented at CERN, the ATLAS Experiment's search for supersymmetry (SUSY) reached new levels of sensitivity. [12] The ATLAS Collaboration at CERN has just released the first open dataset from the Large Hadron Collider's (LHC) highest-energy run at 13 teraelectronvolts (TeV). [11] The Higgs boson was discovered in 2012 by the ATLAS and CMS Experiments at CERN, but its coupling to other particles remains a puzzle. [10] Higgs boson decaying into bottom quarks. Now, scientists are tackling its relationship with the top quark. [9] Usha Mallik and her team used a grant from the U.S. Department of Energy to help build a sub-detector at the Large Hadron Collider, the world's largest and most powerful particle accelerator, located in Switzerland. They're running experiments on the sub-detector to search for a pair of bottom quarks-subatomic yin-and-yang particles that should be produced about 60 percent of the time a Higgs boson decays. [8] A new way of measuring how the Higgs boson couples to other fundamental particles has been proposed by physicists in France, Israel and the US. Their technique would involve comparing the spectra of several different isotopes of the same atom to see how the Higgs force between the atom's electrons and its nucleus affects the atomic energy levels. [7] The magnetic induction creates a negative electric field, causing an electromagnetic inertia responsible for the relativistic mass change; it is the mysterious Higgs Field giving mass to the particles. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate by the diffraction patterns. The accelerating charges 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 Relativistic Quantum Theories. The self maintained electric potential of the accelerating charges equivalent with the General Relativity space-time curvature, and since it is true on the quantum level also, gives the base of the Quantum Gravity. 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.

Quantum entanglement, a term coined by Erwin Schrodinger in 1935, is a mechanical
phenomenon at the quantum level wherein the quantum states of two (or more) particles have
to be described with reference to each other though these particles may be spatially separated. This phenomenon leads to paradox and has puzzled us for a long time. The behaviour of entangled particles is apparently inexplicable, incomprehensible and like magic at work. Locality has been a reliable and fruitful principle which has guided us to the triumphs of twentieth century physics. But the consequences of the local laws in quantum theory could seem “spooky” and nonlocal, with some theorists questioning locality itself. Could two subatomic particles on opposite sides of the universe be really instantaneously connected? Is any theory which predicts such a connection essentially flawed or incomplete? Are the results of experiments which demonstrate such a connection being misinterpreted? These questions challenge our most basic concepts of spatial distance and time. Modern physics is in the process of dismantling the space all around us and the universe will never be the same. Quantum entanglement involves the utilisation of cutting edge technology and will bring great benefits to society. This paper traces the development of quantum entanglement and
presents some possible explanations for the strange behaviour of entangled particles.

Charles Horowitz and Rudolf Widmer-Schnidrig, two researchers at Indiana University and the Black Forest Observatory (BFO) in Germany, respectively, have recently carried out a study investigating the use of gravimeters to search for compact dark matter objects (CDOs) inside the Earth. [25] Superconducting nanowires could be used as both targets and sensors for the direct detection of dark matter, physicists in Israel and the US have shown. [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] 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.

Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy with 100% efficiency—never losing any to heat or friction. [20]
Scientists at the U.S. Department of Energy's Ames Laboratory have developed a method to accurately measure the "exact edge" or onset at which a magnetic field enters a superconducting material. [19]
TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around-200°C [18] The emerging field of spintronics leverages electron spin and magnetization. [17] The first known superconductor in which spin-3/2 quasiparticles form Cooper pairs has been created by physicists in the US and New Zealand. [16] Now a team of researchers from the University of Maryland (UMD) Department of Physics together with collaborators has seen exotic superconductivity that relies on highly unusual electron interactions. [15] A group of researchers from institutions in Korea and the United States has determined how to employ a type of electron microscopy to cause regions within an iron-based superconductor to flip between superconducting and non-superconducting states. [14] In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage. [13] Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. [12] Researchers at the University of Central Florida have generated what is being deemed the fastest light pulse ever developed. [11] Physicists at Chalmers University of Technology and Free University of Brussels have now found a method to significantly enhance optical force. [10] Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. [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.

Now researchers from the MPSD and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials. [55] Cuprates, a class of copper-oxide ceramics that share a common building block of copper and oxygen atoms in a flat square lattice, have been studied for their ability to be superconducting at relatively high temperatures. [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.

[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.

[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.

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.

This result, from researchers in Japan, France and the UK, contradicts the generally-held notion that only hydrogen or helium atoms are light enough to migrate through materials in this way. [32] A new approach developed by researchers at MIT could provide a significant step forward in quantum error correction. [31] EU-funded scientists have succeeded in redefining the ampere in terms of fundamental constants of physics. [30] Tarucha, the leader of the team, says, "This is a very exciting finding, as it could potentially help to accelerate research into scaling up semiconductor quantum computers, allowing us to solve scientific problems that are very tough on conventional computer systems." [29] Physicists at Saarland University in Saarbrücken, Germany, have succeeded in entangling a single atom with a single photon in the telecom wavelength range. [28] A team of physicists from ICTP-Trieste and IQOQI-Innsbruck has come up with a surprisingly simple idea to investigate quantum entanglement of many particles. [27] For the first time, physicists have experimentally demonstrated ternary-rather than binary-quantum correlations between entangled objects. [26] The physicists, Sally Shrapnel, Fabio Costa, and Gerard Milburn, at The University of Queensland in Australia, have published a paper on the new quantum probability rule in the New Journal of Physics.

To develop futuristic technologies like quantum computers, scientists will need to find ways to control photons, the basic particles of light, just as precisely as they can already control electrons, the basic particles in electronic computing. [33] Physicists from the National Institute of Standards and Technology (NIST) and their colleagues have achieved a major new feat-creating a bizarre "quantum" interference between two photons of markedly different colors, originating from different buildings on the University of Maryland campus. [32] Physicists at C2N have demonstrated for the first time the direct generation of light in a state that is simultaneously a single photon, two photons, and no photon at all. [31] A team of researchers from Xiamen University, the University of Ottawa and the University of Rochester has shown that it is possible to entangle photons with correlations between their radial and momentum states. [30] In a new study, researchers demonstrate creative tactics to get rid of loopholes that have long confounded tests of quantum mechanics. [29] This is a very interesting quantum phenomenon called "magnon crystallization," in which the magnons are said to be in a "frustrated" state. [28] In a new paper, have proposed the first practical protocol for anonymous communication in quantum networks. [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]

QuTech has resolved a major issue on the road toward a working large-scale quantum computer. [56] In quantum computing, as in team building, a little diversity can help get the job done better, computer scientists have discovered. [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.

Researchers in China led by Lilin Yi at Shanghai Jiao Tong University developed apparatus and software algorithms allowing automatic 'intelligent control' over the femtosecond pulses generated by mode-locked fiber lasers. [50] Researchers in Australia have found a way to manipulate laser light at a fraction of the cost of current technology. [49] The proposed design breaks the current bandwidth limit in the transmission-type coding metasurfaces, indicating wide application potentials in radar and wireless communication systems. [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] A tiny laser comprising an array of nanoscale semiconductor cylinders (see image) has been made by an all-A*STAR team. [42] A new instrument lets researchers use multiple laser beams and a microscope to trap and move cells and then analyze them in real-time with a sensitive analysis technique known as Raman spectroscopy.

The development of next generation solar power technology that has potential to be used as a flexible 'skin' over hard surfaces has moved a step closer, thanks to a significant breakthrough at The University of Queensland. [29] University of Toronto Engineering researchers have combined two emerging technologies for next-generation solar power-and discovered that each one helps stabilize the other. [28] Photoresponsive flash memories made from organic field-effect transistors (OFETs) that can be quickly erased using just light might find use in a host of applications, including flexible imaging circuits, infra-red sensing memories and multibit-storage memory cells. [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. [21] In the September 23th issue of the Physical Review Letters, Prof. Julien Laurat and his team at Pierre and Marie Curie University in Paris (Laboratoire Kastler Brossel-LKB) report that they have realized an efficient mirror consisting of only 2000 atoms. [20] Physicists at MIT have now cooled a gas of potassium atoms to several nanokelvins-just a hair above absolute zero-and trapped the atoms within a two-dimensional sheet of an optical lattice created by crisscrossing lasers. Using a high-resolution microscope, the researchers took images of the cooled atoms residing in the lattice. [19]

Scientists at the U.S. Department of Energy's Ames Laboratory have discovered that applying vibrational motion in a periodic manner may be the key to preventing dissipations of the desired electron states that would make advanced quantum computing and spintronics possible. [34] For the first time, a group of researchers from Universidad Complutense de Madrid, IBM, ETH Zurich, MIT and Harvard University have observed topological phases of matter of quantum states under the action of temperature or certain types of experimental imperfections. [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]

Yu-Hwa Lo and colleagues at the University of California in San Diego (UCSD) now report on systematic investigations of how these devices respond to light for frequencies varying over eight orders of magnitude and power ranging from millions to single photons. [20] A new joint Tel Aviv University (TAU) and Karlsruhe Institute of Technology (KIT) study published in Nature Communications on February 28 demonstrates remarkable continuous lasing action in devices made from perovskites. [19] Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published in Nature Photonics. [18] Very recently, an NTU team lead by Assoc. Prof. Wang Hong, demonstrated high light extraction efficiency of perovskite photonic crystals fabricated by delicate electron-beam lithography. [17] A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' which affects the fundamental properties of many systems in condensed matter physics. [16] Researchers have recently been also interested in the utilization of antiferromagnets, which are materials without macroscopic magnetization but with a staggered orientation of their microscopic magnetic moments. [15] A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics. [14] The emerging field of spintronics aims to exploit the spin of the electron. [13] In a new study, researchers measure the spin properties of electronic states produced in singlet fission-a process which could have a central role in the future development of solar cells. [12] In some chemical reactions both electrons and protons move together. When they transfer, they can move concertedly or in separate steps. Light-induced reactions of this sort are particularly relevant to biological systems, such as Photosystem II where plants use photons from the sun to convert water into oxygen. [11]

After years of preparation, a team at the TU Wien managed to conduct an experiment in which the spin of a neutron traverses through a region with a rotating magnetic field. [41] "The so-called 'quantum thermodynamics' are currently under development," Roberto Serra, one of the researchers who carried out the study, told Phys.org. [40] A team of scientists from the Research Center "Fundamental Problems of Thermophysics and Mechanics," of Samara Polytech is engaged in the construction of new mathematical models and the search for methods for their study in relation to a wide range of local nonequilibrium transport processes in various physical systems. [39] Researchers at the Center for Soft and Living Matter, within the Institute for Basic Science (IBS, South Korea) found that the temperature increase caused by the probe beam could be utilized to generate a signal per se for detecting objects. [38] Scientists at the University of Würzburg have been able to boost current super-resolution microscopy by a novel tweak. [37] "We put the optical microscope under a microscope to achieve accuracy near the atomic scale," said NIST's Samuel Stavis, who served as the project leader for these efforts. [36] Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. [35] A technique to manipulate electrons with light could bring quantum computing up to room temperature. [34] The USTC Microcavity Research Group in the Key Laboratory of Quantum Information has perfected a 4-port, all-optically controlled non-reciprocal multifunctional photonic device based on a magnetic-field-free optomechanical resonator. [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.

A new approach developed by researchers at MIT could provide a significant step forward in quantum error correction. [31] EU-funded scientists have succeeded in redefining the ampere in terms of fundamental constants of physics. [30] Tarucha, the leader of the team, says, "This is a very exciting finding, as it could potentially help to accelerate research into scaling up semiconductor quantum computers, allowing us to solve scientific problems that are very tough on conventional computer systems." [29] Physicists at Saarland University in Saarbrücken, Germany, have succeeded in entangling a single atom with a single photon in the telecom wavelength range. [28] A team of physicists from ICTP-Trieste and IQOQI-Innsbruck has come up with a surprisingly simple idea to investigate quantum entanglement of many particles. [27] For the first time, physicists have experimentally demonstrated ternary-rather than binary-quantum correlations between entangled objects.

[31] KAIST researchers have reported the detection of a picosecond electron motion in a silicon transistor. [30] In quantum physics, some of the most interesting effects are the result of interferences.

A magnetic monopole is a theoretical particle with a magnetic charge. Give it an electric charge, and you get another theoretical beast, dubbed a dyon. [32] Such devices would use magnetic films and superconducting thin films to deploy and manipulate magnetic monopoles to sort and store data based on the north or south direction of their poles-analogous to the ones and zeros in conventional magnetic storage devices. [31] The vacuum is filled with quantum fluctuations of the electromagnetic field-virtual photons that pop in and out of existence-that are assumed to behave in the same way. To make the plates repulsive and tunable, Wilczek and Stockholm University colleague Qing-Dong Jiang inserted a material between the plates that breaks this behavior. [30] In terms of physics, the interiors of neutron stars, cold atomic gasses and nuclear systems all have one thing in common: they are gaseous systems made up of highly interactive, superfluid fermions. [29] Engineers at MIT and Penn State University have found that under the right conditions, ordinary clear water droplets on a transparent surface can produce brilliant colors, without the addition of inks or dyes.

We conceive the universe as determinate, subject always to the Laws of Nature. We cannot prove this, but it can be shown to be our only viable opption. In which case there is no such thing as chance, and objectively speaking we are all determined. But since in practice we cannot predict the universe's future course – principally because we ourselves are part of it – subjectively we experience the universe as indeterminate and ourselves as free.

Currently, natural philosophy (Physics) lacks the most fundamental model and a complete set of self-consistent explanations. This article attempts to discuss several issues related to this lack. 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, and its simple verification is carried out. 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.

互能流理论简称“互能论”是包括互能定理，互能流定理互能原理，自能原理的一套从微观到宏观的电磁理论。该理论的目的是告诉我们光子是怎样由波构成的。宏观的电磁波又是怎样由光子进一步构成。因此对量子力学的波粒二象性悖论给出了一个很好的解决方案。按照互能论，构成光子的波有滞后波，超前波，还有两个时间反转波。滞后波超前波满足麦克斯韦方程。滞后波同超前波叠加其能流由两部分互能流和自能流构成。自能流是滞后波自身的能量流和超前波自身的能量流。互能流是滞后波同超前波的相互作用的附加能量流。自能原理告诉我们电磁场有两个时间反转波抵消了滞后波的自能流和超前波的自能流。这样自能流不传递能量。因此光源发出的滞后波是概率波，不是能流波。能量只是由互能流传递的。互能流经过归一化构成光子。因此能量流是由光子携带。互能流满足互能定理，和互能流定理。互能定理告诉我们，辐射源电荷的滞后波对吸收体电荷做的功正好等于吸收体产生的超前波在辐射体上吸允的功。互能流定理告诉我们在辐射体同吸收体之间有一个能量流，这个能量流所携带的能量通过在辐射体同吸收体之间的任何一个截面都是相同的。从互能原理可以推导互能定理，互能流定理，麦克斯韦方程，时间反转的麦克斯韦方程。互能原理，自能原理是这套电磁场理论的新公理。本文回顾作者完成这套理论的全过程。这个过程分为两个部分，第一部分是作者1987年到1989年间发表的互能定理。第二部分是2014年开始到2019年作者第二次进入这个课题最终彻底完成的互能论。在完成了电磁场的互能论后，作者把这一理论也推广到量子力学。这样任何一给粒子都是由互能流构成的。互能流是由对应粒子的波比如满足薛定谔方程的波的滞后波同超前波构成的。归一化后互能流就是粒子。构成粒子也有时间反转波。时间反转波抵消了所有自能流的能流，使得波成为概率波，而非能量波。能量是由粒子传递。反粒子由时间反转波的互能流构成。粒子的情况同光子近似。
The theory of mutual energy flow referred to as "mutual energy theory" is a set of electromagnetic theories from micro to macro including the theory of mutual energy, the principle of mutual energy, and the principle of self energy. The purpose of this theory is to tell us how photons are made up of waves. Therefore, a good solution is given to the wave-particle duality paradox of quantum mechanics. According to the theory of mutual energy, the waves that make up a photon include a retarded wave, an advanced wave, and two time-reversing waves. The retarded wave and the advanced wave satisfy the Maxwell equation. The energy flow of a retarded wave and an advanced wave is composed of two parts of a mutual energy flow and a self-energy flow. The self-energy flow is the energy flow of the retarded wave itself and the energy flow of the advanced wave itself. Mutual energy flow is the energy flow that interacts with a retarded wave and an advanced wave. The principle of self-energy tells us that two time-reversed waves in an electromagnetic field cancel out the self-energy flow of the retarded wave and the self-energy flow of the advanced wave. In this way, self-energy flow does not transfer energy. Therefore, electromagnetic waves are probability waves, not energy waves. Energy is only transferred by mutual energy flow. Mutual energy flows are normalized to form photons. So the energy flow is carried by photons. The mutual energy flow satisfies the mutual energy theorem, and the mutual energy flow theorem. The mutual energy theorem tells us that the work of the retarded wave of the emitting source charge on the charge of the absorber is exactly equal to the work that the advanced wave generated by the absorber absorbs on the emitter. The mutual energy flow theorem tells us that there is an energy flow between the emitter and the absorber. The energy carried by this energy flow is the same through any cross section between the emitter and the absorber. By using the principle of mutual energy, the mutual energy theorem, the mutual energy flow theorem, Maxwell's equation, and Maxwell's equation of time reversal can be derived. The principle of mutual energy and the principle of self-energy are the new axioms of this electromagnetic field theory. This article reviews the author's entire process of completing this theory. This process is divided into two parts. The first part is the mutual energy theorem published by the author from 1987 to 1989. The second part is the theory of mutual energy that the author entered this topic for the second time from 2014 to 2019. After completing the theory of mutual energy of electromagnetic fields, the author extended this theory to quantum mechanics. In this way, any given particles are composed of mutual energy flows. The mutual energy flow is composed of the retarded wave and the advanced wave of the wave of the corresponding particle, such as a wave satisfying the Schrodinger equation. The normalized mutual energy flow is the particle. The constituent particles also have time-reversed waves. Time-reversed waves cancel out all the energy flows of the self-energy flow, making the wave a probability wave rather than an energy wave. Energy is delivered by particles. Antiparticles consist of a mutual energy flow of time-reversed waves. The situation of particles is similar to that of photons.

This paper recaps our electron model – including our explanation of the anomaly – and offers some reflections on Nature’s fundamental constants. We will also present a theoretical explanation of the radius of the Zitterbewegung charge – aka the classical electron radius – using an electromagnetic mass calculation. While, in the previous version of the paper, we limited ourselves to a classical (non-mainstream) explanation of Schwinger’s α/2π factor, we also offer some reflections on a possible explanation of the higher-order factors in the anomaly of the magnetic moment of an electron. Finally, we offer some reflections on the distinction between the spin and orbital angular momentum of an electron.

Researchers from Graz University of Technology and the University of Vienna have better described the energy flow between strongly interacting molecular states. [43] Research in Stuttgart, have developed a microscope for the extremely fast processes that take place on the quantum scale. [42] 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.

As air travel comes under pressure to reduce its environmental impact and prompts us to reconsider our transport choices, scientists are searching for greener ways to power flight. [20]
Scientists at the U.S. Department of Energy's Ames Laboratory have developed a method to accurately measure the "exact edge" or onset at which a magnetic field enters a superconducting material. [19]
TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around-200°C [18] The emerging field of spintronics leverages electron spin and magnetization. [17] The first known superconductor in which spin-3/2 quasiparticles form Cooper pairs has been created by physicists in the US and New Zealand. [16] Now a team of researchers from the University of Maryland (UMD) Department of Physics together with collaborators has seen exotic superconductivity that relies on highly unusual electron interactions. [15] A group of researchers from institutions in Korea and the United States has determined how to employ a type of electron microscopy to cause regions within an iron-based superconductor to flip between superconducting and non-superconducting states. [14] In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage. [13] Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. [12] Researchers at the University of Central Florida have generated what is being deemed the fastest light pulse ever developed. [11] Physicists at Chalmers University of Technology and Free University of Brussels have now found a method to significantly enhance optical force. [10] Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. [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.

"Powering a topological superconductor using a time crystal gives you more than the sum of its parts," says Jason Alicea, a researcher at California Institute of Technology (Caltech) in the US. [26]
Dreamt up by the physics Nobel laureate Frank Wilczek in 2012, the notion of “time crystals” is now moving from theory to experiment – and could also lead to applications such as a new kind of atomic clock. [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]
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]

In 1913, a Danish scientist named Niels Bohr introduced a formula that explained the spectral lines of hydrogen atoms, which was simple and important to get a picture of the model of atoms.
Nevertheless, it is difficult to treat the electron motion of an atom with Newtonian kinematics and use it as a formula for calculating the energy level of an electron in an atom with a large atomic number.
Thus, the formula was created with relativity, which is very simple to learn and good for teaching.

The experiment measured the absorption of single photons by absorbers with various absorption coefficients, in one of the beams, after the photons interacted with the beam splitter. The measurements showed that the absorption corresponds to single photon traveling in either one or another beam. The results of our measurements and of single photon interference experiments, combined together, demonstrate the existence of the empty waves. We show that seemingly justified criticism of our interpretation of the experiment is not valid. New experiments are proposed to study single-photon interference involving an empty wave.

Quantum engineers from UNSW Sydney have created artificial atoms in silicon chips that offer improved stability for quantum computing. [58] Prospective digital data storage devices predominantly rely on novel fundamental magnetic phenomena. [57] Scientists at Linköping University have shown how a quantum computer really works and have managed to simulate quantum computer properties in a classical computer. [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] 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.

Researchers at the University of Münster and Forschungszentrum Jülich now, for the first time, demonstrated what is known as energy quantization in nanowires made of high-temperature superconductors-i. e. superconductors, in which the temperature is elevated below which quantum mechanical effects predominate. [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.

High magnetic fields have a potential to modify the microscopic arrangement of magnetic moments because they overcome interactions existing in a zero field. [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.

This article discusses the concept of g-factors and anomalies in the context of the ring current or Zitterbewegung model of elementary particles. We suggest the anomalies are not anomalies at all. We think that the assumption that the pointlike zbw charge has no dimension or structure whatsoever is bound to yield these so-called anomalies between our measurements (mainly of the charge radius and the magnetic moment) and the nice theories we have about the structure of elementary particles. We illustrate the theory using the classical calculations for the electron.
We then discuss the results of the 2019 PRad experiment, which yielded a point estimate of about 0.831 fm. While this value differs only slightly from the 0.841 value that was measured by Pohl (2010) and Antognini (2013), we think the PRad value is very interesting, because it is very consistent with the anomalies (radius as well as magnetic moment) one can calculate. We think it confirms that the PRad measurement is very solid.

[43] A nanoscale gold butterfly provides a more precise route for growing/synthesizing nanosized semiconductors that can be used in nano-lasers and other applications. [42] Magnetic vortices are nanoscale whirls that gyrate like spinning tops, tracing out paths in a clockwise or counterclockwise manner in nanometer-thick materials. [41] Now a team of Australian scientists has discovered diamond can be bent and deformed, at the nanoscale at least. [40] Researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) have fabricated a novel glass and synthetic diamond foundation that can be used to create miniscule micro-and nanostructures. [39] Osaka University-led researchers demonstrated that the perturbation of laser imprinting on a capsule for nuclear fusion fuel made from stiff and heavy materials was mitigated. [38] Scientists found that relatively slow electrons are produced when intense lasers interact with small clusters of atoms, upturning current theories. [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.

Scientists from Far Eastern Federal University (FEFU, Vladivostok, Russia), together with colleagues from FEB RAS, China, Hong Kong, and Australia, manufactured ultra-compact bright sources based on IR-emitting mercury telluride (HgTe) quantum dots (QDs), the future functional elements of quantum computers and advanced sensors. [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] 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]

Calculations performed by an international team of researchers from Spain, Italy, France, Germany, and Japan show that the crystal structure of the record superconducting LaH10 compound is stabilized by atomic quantum fluctuations. [20] Scientists at the U.S. Department of Energy's Ames Laboratory have developed a method to accurately measure the "exact edge" or onset at which a magnetic field enters a superconducting material. [19] TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around-200°C [18] The emerging field of spintronics leverages electron spin and magnetization. [17] The first known superconductor in which spin-3/2 quasiparticles form Cooper pairs has been created by physicists in the US and New Zealand. [16] Now a team of researchers from the University of Maryland (UMD) Department of Physics together with collaborators has seen exotic superconductivity that relies on highly unusual electron interactions. [15] A group of researchers from institutions in Korea and the United States has determined how to employ a type of electron microscopy to cause regions within an iron-based superconductor to flip between superconducting and non-superconducting states. [14] In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage. [13] Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. [12] Researchers at the University of Central Florida have generated what is being deemed the fastest light pulse ever developed. [11] Physicists at Chalmers University of Technology and Free University of Brussels have now found a method to significantly enhance optical force. [10] Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. [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.

Researchers using CERN's nuclear-physics facility ISOLDE have now stepped into this nearly uncharted region of the nuclear chart with a first study of the neutron structure of the mercury isotope 207 Hg. [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.

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]

[21] Search engine entropy is thus important not only for the efficiency of search engines and those using them to find relevant information as well as to the success of the companies and other bodies running such systems, but also to those who run websites hoping to be found and visited following a search. [20] "We've experimentally confirmed the connection between information in the classical case and the quantum case," Murch said, "and we're seeing this new effect of information loss." [19]

3-Dimensional Rigid Transformer Strings with Composite Topological Strings

Abstract,
In particle physics it is an interesting challenge to postulate that the FORM and structure of elementary particles is the origin of different FUNCTIONS of these particles.
In this paper we present a possible solution based on complex 3-D ring shaped particles, which are equipped with three point like hinges and one splitting point, all four locations divided equally over the ring surface.
The 3-D ring itself is postulated to represent the “Virgin Mother” of all other particles and is coined Axion Higgs particle, supplied with the 3-hinges coded (OOO), which gives the particle the opportunity to transform after real mechanical collision with other particles into a different shape, with a different function.
Thus in this Quantum Function Follows Form theory, (Q-FFF) the Axion Higgs is interpreted as a massless transformer particle able to create the universe by transforming its shape after real mechanical collision and merge with other shaped particles into composite and compound knots.

"We have found a new way to switch the electrical conduction in materials from on to off," said lead author Berend Zwartsenberg, a Ph.D. student at UBC's Stewart Blusson Quantum Matter Institute (SBQMI). [45] Researchers at the University of Chicago and Argonne National Laboratory have invented an innovative way for different types of quantum technology to "talk" to each other using sound. [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]

A collaboration between McMaster and Harvard researchers has generated a new platform in which light beams communicate with one another through solid matter, establishing the foundation to explore a new form of computing. [35] An international team of physicists from the Mandelstam Institute for Theoretical Physics at Wits University and the Institut Néel in Grenoble, France, has created a tiny superconducting circuit that mimics the quantum mechanical process in which an atom absorbs or emits light. [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]

That's why physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory studying a well-known cuprate containing layers made of bismuth oxide, strontium oxide, calcium, and copper oxide (BSCCO) decided to focus on the less complicated "overdoped" side, doping the material so much so that superconductivity eventually disappears.

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.

Now, an international team of scientists has discovered an exotic new form of topological state in a large class of 3-D semi-metallic crystals called Dirac semimetals. [34]
For the first time, a group of researchers from Universidad Complutense de Madrid, IBM, ETH Zurich, MIT and Harvard University have observed topological phases of matter of quantum states under the action of temperature or certain types of experimental imperfections. [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]

This paper discusses when space is flowing into or out of a universe from the multiverse. Particularly, it discusses how this inflow produced gravitational hills and wells in our Universe. These gravitational hills and wells had the same effect on clumping matter as the proposed dark matter.

This paper proposes a strong variant of ER=EPR conjecture (svEEC) based on Planck wormholes (PWs) (and partially assuming Einstein’s General Relativity), which svEEC helps redefining both big G and Planck constant, potentially explaining both the accelerated expansion of our universe (OU) and the highly variable experimental values of big G. This paper continues (from alternative angles of view!) the work of other past articles/preprints of the same author.

Researchers at the Institute of Photonic Sciences in Spain have now overcome these flaws by constructing a mercury-free colloidal quantum dot (CQD) device that can detect light across these difficult-to-access wavelengths. [31] In their experiment, the researchers used a technique to electronically dope the quantum dots robustly and permanently. [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. [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.

One of the cornerstones of quantum theory is a fundamental limit to the precision with which we can know certain pairs of physical quantities, such as position and momentum. [56] We don't have to get into what they claimed was the mechanism for destroying interference, because our experiment has shown there is an effect on the velocity of the particle, of just the size Heisenberg predicted. [55] Physicists have proposed an entirely new way to test the quantum superposition principle-the idea that a quantum object can exist in multiple states at the same time. [54] Researchers have developed a new device that can measure and control a nanoparticle trapped in a laser beam with unprecedented sensitivity. [53] Researchers have discovered a 'blind spot' in atomic force microscopy-a powerful tool capable of measuring the force between two atoms, imaging the structure of individual cells and the motion of biomolecules. [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]

This paper proposes a set of relatively new conjectures and hypotheses in modern physics, mainly concept of subquantum movement (SQM), the finite “elasticity” of (charged/neutral) spacetime hypothesis (FESTH) (a unifying concept which may bring under the “same umbrella” both Einstein’s General relativity [EGR] and Quantum Field Theory [QFT]), the self-repulsiveness of electromagnetic charge (SR-EMC) and the gravitational significance (GS) of the fine structure constant (GS-FSC): each conjecture (or hypothesis) in part is based on at least one observation and generates some interesting predictions. This paper continues (from alternative angles of view!) the work of other past articles/preprints of the same author.

Theoretical physicists from Trinity College Dublin have found a deep link between one of the most striking features of quantum mechanics-quantum entanglement-and thermalisation, which is the process in which something comes into thermal equilibrium with its surroundings. [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. [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.
