To the human eye, most stationary objects appear to be just that -- still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, what was an apple sitting idly on our desk would appear as a teeming collection of vibrating particles, very much in motion. In the last few decades, physicists have found ways to … [Read more...] about Physicists bring human-scale object to near standstill, reaching a quantum state: The results open possibilities for studying gravity’s effects on relatively large objects in quantum states

A team of scientists headed by SANKEN (The Institute of Scientific and Industrial Research) at Osaka University demonstrated that single virus particles passing through a nanopore could be accurately identified using machine learning. The test platform they created was so sensitive that the coronaviruses responsible for the common cold, SARS, MERS, and COVID could be … [Read more...] about Highly sensitive test for SARS-CoV-2 may enable rapid point-of-care testing for COVID

Electrons are ubiquitous among atoms, subatomic tokens of energy that can independently change how a system behaves -- but they also can change each other. An international research collaboration found that collectively measuring electrons revealed unique and unanticipated findings. The researchers published their results on May 17 in Physical Review Letters. "It is not … [Read more...] about Defining the Hund physics landscape of two-orbital systems

AI is used in an array of extremely useful applications, such as predicting a machine's lifetime through its vibrations, monitoring the cardiac activity of patients and incorporating facial recognition capabilities into video surveillance systems. The downside is that AI-based technology generally requires a lot of power and, in most cases, must be permanently connected to the … [Read more...] about AI system-on-chip runs on solar power

As almost all our private information is digitalized, it is increasingly important that we find ways to protect our data and ourselves from being hacked. Quantum Cryptography is the researchers' answer to this problem, and more specifically a certain kind of qubit -- consisting of single photons: particles of light. Single photons or qubits of light, as they are also called, … [Read more...] about New invention keeps qubits of light stable at room temperature

Research led by the University of Kent and the STFC Rutherford Appleton Laboratory has resulted in the discovery of a new rare topological superconductor, LaPt3P. This discovery may be of huge importance to the future operations of quantum computers. Superconductors are vital materials able to conduct electricity without any resistance when cooled below a certain temperature, … [Read more...] about New discovery of a rare superconductor may be vital for the future of quantum computing

Researchers from The Australian National University (ANU) have developed new technology that allows people to see clearly in the dark, revolutionising night-vision. The first-of-its-kind thin film, described in a new article published in Advanced Photonics, is ultra-compact and one day could work on standard glasses. The researchers say the new prototype tech, based on … [Read more...] about Let there be light! New tech to revolutionize night vision: Ultra-thin film could one day be used on reading glasses

Optical cloaking allows objects to be hidden in plain sight or to become invisible by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, like in the "Harry Potter" books, researchers in recent years have started realizing cloaks that shield objects from view by controlling the flow of electromagnetic radiation around them. In … [Read more...] about Bending light for safer driving; invisibility cloaks to come? Optical cloaks hide objects in plain view by controlling the flow of electromagnetic radiation around them

The phenomenon of quantum nonlocality defies our everyday intuition. It shows the strong correlations between several quantum particles some of which change their state instantaneously when the others are measured, regardless of the distance between them. While this phenomenon has been confirmed for slow moving particles, it has been debated whether nonlocality is preserved … [Read more...] about Quantum-nonlocality at all speeds

Magnetic-spin interactions that allow spin-manipulation by electrical control allow potential applications in energy-efficient spintronic devices. An antisymmetric exchange known as Dzyaloshinskii-Moriya interactions (DMI) is vital to form various chiral spin textures, such as skyrmions, and permits their potential application in energy-efficient spintronic devices. Published … [Read more...] about Inducing and tuning spin interactions in layered material: Spin-manipulation permits potential applications in energy-efficient spintronics
