Entanglement-enhanced optical lattice clock achieves unprecedented precision

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference ...

China breaks final bottleneck in realizing nuclear clock, extending ultra-stable laser technology into vacuum ultraviolet for the first time

Chinese research team achieved a major breakthrough in continuous-wave vacuum ultraviolet (VUV) light sources, a longstanding bottleneck in the development of the nuclear clock, Science and Technology ...
