Quantum Physics

This obvious distinction between the liquid and solid states of substances is something that we all experience on a daily basis—water flows; ice is rigid. It follows from the exceptionally ordinary plan of iotas and atoms in translucent solids, which is lost when they dissolve. In any case, less clear is the design of "fluid precious stones,"  profoundly fascinating states that consolidate request and turmoil so that significant applications like LCDs (fluid gem shows) are conceivable. Together with colleagues from Kiel University (CAU), the Deutsches Elektronen Sychrotron (DESY), and the University of Göttingen, researchers at the Max Planck Institute (MPI)

Quantum entanglement is a phenomenon that occurs in quantum mechanics where two or more particles become correlated in such a way that the state of one particle cannot be described independently of the state of the other particles, even when they are physically separated by large distances. The “spooky action at a distance” that once alarmed Einstein may soon become as commonplace as the gyroscopes used in today's smartphones to monitor acceleration. A recent study published in Nature Photonics shows that quantum entanglement dramatically increases the accuracy of sensors that can be used to navigate without GPS. “By exploiting entanglement,

Caltech researchers have found a way to enhance the resolution of light microscopes using a “spooky” quantum physics phenomena. A team led by Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, demonstrates the advancement of microscopy through the phenomenon known as quantum entanglement in research that will be published in the journal Nature Communications. A phenomenon known as quantum entanglement occurs when two particles are connected in such a way that their states are inextricably linked, regardless of how far apart they are from one another. Albert Einstein famously referred to quantum entanglement as “spooky action at a

Petr Steindl, a doctoral candidate, uses single photons to construct intricate light structures. As a youngster, he needed to concentrate on Czech verse, but settled on quantum material science. "Thinking back, I'm happy I exchanged fields," he says. On July 5, he will present his theory on quantum optics and quantum spot frameworks. According to Steindl, "a quantum dot is simply a little island of semiconducting material." It experiences quantum effects in the same way that an atom does because it is only a few nanometers in size." The scientist puts this quantum dab in an optical microcavity to more

A novel microwave isolator has been developed by researchers at the National Astronomical Observatory of Japan (NAOJ), and its fundamental principle, which enables small isolators, has been demonstrated for the first time. This is essential for quantum computers in the future. Two frequency mixers make up this isolator, which paves the way for the creation of large-scale multi-pixel radio cameras as well as receivers for radio telescopes. The paper is distributed in the IEEE Microwave and Remote Innovation Letters. An electronic part called an isolator is used in quantum computers and radio receivers for astronomy to control the direction in

On the website of an unknown merchant, have you ever been forced to enter sensitive payment information? Would you be willing to hand over passwords or information about your credit card to someone you don't trust? Researchers from the College of Vienna have now planned a genuinely solid framework for shopping in such settings, consolidating current cryptographic strategies with the essential properties of quantum light. Nature Communications has published a demonstration of these "quantum-digital payments" in a real-world setting. In many areas of our daily lives, physical banknotes have been replaced by digital payments. They should be easy to use,

The researchers at EPFL demonstrate that a quantum machine-learning model known as "quantum neural networks" can learn and predict the behavior of quantum systems from a small number of straightforward examples, bringing us one step closer to a new era of quantum computing. Imagine a world in which computers are able to decipher the mysteries of quantum mechanics, allowing us to study the behavior of intricate materials and accurately simulate the intricate dynamics of molecules. We are now a step closer to making that a reality as a result of a ground-breaking study conducted by Professor Zoe Holmes and her

The Rydberg state is common in atoms, molecules, and solids, among other physical platforms. In particular, Rydberg excitons are electron-hole pair, highly excited Coulomb-bound states that were first discovered in the 1950s in the semiconductor material Cu2O. Rydberg moiré excitons, which are moiré-trapped Rydberg excitons in the monolayer semiconductor WSe2 adjacent to small-angle twisted bilayer graphene (TBG), were observed by Dr. Xu Yang and his colleagues from the Institute of Physics of the Chinese Academy of Sciences (CAS) in collaboration with researchers led by Dr. Yuan Shengjun of Wuhan University in a study that was recently published in Science. A

If you are unable to read the computer's output, what use is it? Or can it be easily programmed to perform various tasks? These difficulties are faced by designers of quantum computers, and a new device may make them simpler to overcome. The gadget, presented by a group of researchers at the Public Establishment of Guidelines and Innovation (NIST), incorporates two superconducting quantum bits, or qubits, which are a quantum PC's equivalent to the rationale bits in a traditional PC's handling chip. A "toggle switch" device is at the center of this new strategy. It connects the qubits to a

Non-Markovian behaviors of Einstein-Podolsky-Rosen (EPR) steering in quantum processes were investigated by a team led by Guo Guangcan from the Chinese Academy of Sciences (CAS) and revealed the entire evolution of EPR steering in quantum open systems. Physical Review Letters published this piece. EPR steering is a quantum non-local phenomenon in which one party can use local measurements to have non-local effects on the other party's state, which is similar to entanglement and Bell non-locality. One-way EPR steering that can provide resources for quantum information tasks is made possible by its distinctive directional property. The vast majority of previous research
