The clock, which utilizes quantum entanglement of atoms and a different element than most atomic clocks rely on, could be dramatically more accurate over long periods of time than current models.

A top-secret lab in the UK is developing the country's first quantum clock to help the British military boost intelligence and reconnaissance operations, the defense ministry said Thursday. The clock ...
