A calculation may account for the gallium anomaly, in which experiments observed about 20 per cent fewer captured electron neutrinos than expected. The discrepancy was first clearly identified and described in 2007 by Italian neutrino physicist Carlo Giunti.
A new spectroscopy method enables direct comparisons of nuclear charge radii across heavy elements. Charge radii reflect the arrangement of protons and neutrons, and their changes can help researchers study nuclear structure and deformation.
Silicon spin qubits achieved gate fidelity above 99.99% while three qubits operated at once. The platform is compatible with chip-making technologies, but parallel control has typically reduced qubit accuracy.
Auburn University physicists used laser flashes to order electrically charged regions inside a crystal. The finding addresses a decades-old question about the material and points to using light to control its behaviour.
Calculations examine how spin defects in solids change energetically over time, a process that can be difficult to model. The defects could serve as stable, readable qubits for technologies such as quantum sensing.
A proposed quantum sensor could measure frame-dragging, the effect of Earth’s rotation on nearby spacetime predicted by Einstein’s general relativity.
Researchers developed an optical ring-laser gyroscope on a chip that detects rotation as slow as 37 degrees per hour. The technology could eventually support precision navigation and orientation where GPS is unavailable.
A research team led by HKUST professor Haruki Watanabe developed a unified theory to distinguish genuinely different states of matter from states that are actually the same.
CMS and LHCb presented new research on rare beauty-quark decays at the recent International Conference on High Energy Physics. The process turns a beauty quark into a strange quark, a muon and an oppositely charged antimuon, and provides a stringent test of the Standard Model.
IBM Europe and Africa vice-president Alessandro Curioni said organizations are unprepared for risks from quantum computing. He warned the technology could break security encryption and enable large-scale cyberattacks.
Researchers have developed an algorithm that lets off-the-shelf computers run quantum simulations once limited to the world’s most powerful supercomputers. The study suggests the advance could help create larger, more reliable quantum computers.
Researchers have shown that a memory device can come close to the fundamental theoretical limit on the energy it uses. The finding could point to a new kind of ultra-efficient memory.
