When a cavitation bubble in a liquid gets trapped in the antinode — the maximum point of amplitude — of an ultrasonically driven standing wave, it can periodically emit visible photons. Researchers call this sound-to-light […]
Reports from China suggest that scientists there are on the cusp of a new helium-based cooling system that could help quantum computing become more feasible. However, there are still questions on whether the new technique […]
The three organizations have created a Research Hub for Diamond Quantum Materials to focus on atom-scale fabrication techniques for nitrogen-vacancy (NV) centers in diamond. Quantum Brilliance is developing quantum processors using what is called an […]
The funding will be provided by the U.S. Department of Defense (DoD) through the Air Force Research (AFRL) Laboratory located in Rome, New York. This lab has been designated as the Quantum Information Science Research […]
Sensors are a pillar of the Internet of Things, providing the data to control all sorts of objects. Here, precision is essential, and this is where quantum technologies could make a difference. Researchers are now […]
Scientists have achieved the most precise measurement to date of the mass of the W boson, one of nature’s force-carrying particles. The measured value shows tension with the value expected based on the Standard Model […]
Physicists have found that an elementary particle called the W boson appears to be 0.1% too heavy — a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, reported today in […]
The most precise-ever measurement of W boson mass suggests the standard model needs improvement0 (0)
After 10 years of careful analysis and scrutiny, scientists of the CDF collaboration at the U.S. Department of Energy’s Fermi National Accelerator Laboratory announced today that they have achieved the most precise measurement to date […]
Quantum 6, 683 (2022). https://doi.org/10.22331/q-2022-04-07-683 Uncertainty relations play a crucial role in quantum mechanics. Well-defined methods exist for the derivation of such uncertainties for pairs of observables. Other approaches also allow the formulation of time-energy […]
Scientists from The Institute of Scientific and Industrial Research (SANKEN) at Osaka University, in collaboration with the Canadian National Research Council (NRC), developed a gallium arsenide (GaAs) quantum dot that can trap individual electrons. By […]
