The strange quantum nature of time moves one step closer to being untangled, thanks to new research on optical ion clocks.

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 ...

A new generation of optical atomic clocks, some accurate enough to lose less than a second over the entire age of the universe, is driving an international push to replace the cesium-based definition ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

Vector Atomic has launched a rack-mounted atomic clock. The company this week announced the launch of Evergreen-30, which it said is the world’s first fully integrated commercial optical atomic clock.

Physicists have outlined a method to test whether time itself can exist in quantum superposition, allowing a single clock to tick both faster and slower simultaneously. Advances in optical atomic ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years’ time, they could ...
