Mercury atomic clock keeps time with record accuracy

An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a “fountain” of cesium atoms, according to a paper by ...

New optical atomic clock is 1,000x more accurate than today's standard

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...
