EXPERIMENTAL NEXT-GENERATION CHIP-SCALE ATOMIC CLOCK
Physicists at the National Institute of Standards and Technology (NIST) and partners have demonstrated an experimental, next-generation atomic clockâticking at high âopticalâ frequenciesâthat is much smaller than usual, made of just three small chips plus supporting electronics and optics. Described in Optica, the chip-scale clock is based on the vibrations, or âticks,â of rubidium atoms confined in a tiny […]
