Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard ...
Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and develop quantum technologies, ...
Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the "water window." This new method holds promise in making bioimaging ...
