An international team of physicists has identified a new technique for testing the quality of quantum correlations. Quantum computers run their algorithms on large quantum systems by creating quantum correlations across all of them. It is important to verify the quantum correlations achieved are of the desired quality. However, carrying out checks is resource-intensive so the team has proposed a new technique that significantly reduces the number of measurements while increasing the resilience against noise.
A team of scientists from Germany has managed to successfully perform atom interferometry in space for the first time - on board a sounding rocket.
A simple yet elegant change to code studied for more than 20 years could shorten timeline to achieve scalable quantum computation and has attracted the attention of quantum computing programs at Amazon Web Services and Yale University.
Researchers have used a technique similar to MRI to follow the movement of individual atoms in real time as they cluster together to form two-dimensional materials, which are a single atomic layer thick.
The long-awaited first results from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists' best theory, the Standard Model of particle physics.
Most materials go from being solids to liquids when they are heated. One rare counter-example is helium-3, which can solidify upon heating. This counterintuitive and exotic effect, known as the Pomeranchuk effect, may now have found its electronic analogue in a material known as magic-angle graphene, says a team of researchers from the Weizmann Institute of Science led by Prof. Shahal Ilani, in collaboration with Prof. Pablo Jarillo-Herrero's group at the Massachusetts Institute of Technology (MIT).
A new estimation of the strength of the magnetic field around the muon--a sub-atomic particle similar to, but heavier than, an electron--closes the gap between theory and experimental measurements, bringing it in line with the standard model that has guided particle physics for decades.
Researchers at the National Institute of Standards and Technology (NIST) and collaborators have demonstrated an atom-based sensor that can determine the direction of an incoming radio signal, another key part for a potential atomic communications system that could be smaller and work better in noisy environments than conventional technology.
Space scientists at the University of Bath in the UK have found a new way to probe the internal structure of neutron stars, giving clues about the makeup of matter at an atomic level.
Research team from University of Science and Technology of China realized synthetic gauge fields in a single optomechanical resonator, shedding new light on study of photons and realization of topological protection.
