For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more ...

Researchers from six countries conducted the largest coordinated comparison of optical clocks to date. The measurements amount to the largest coordinated comparison of optical clocks to date, and ...

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 ...

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 ...

WASHINGTON — In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...
