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 transportable ytterbium optical lattice clock has been commercially shipped, rapidly recommissioned, and tested against ...

Physicists have developed a highly precise and ultra-sensitive atomic clock based on ytterbium, which ...

Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy transitions in the nuclei of atoms and could become the ...

Add Yahoo as a preferred source to see more of our stories on Google. MIT and Harvard scientists have built the world’s most precise optical clock, surpassing the quantum limit with entangled atoms ...

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 countries.

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 ...

QuantX personnel conducting environmental testing on the optical frequency comb, which is a key optical atomic clock technology that will be launched into space for testing. (QuantX Labs) ...

Rising precision demands and GPS/GNSS vulnerabilities are driving the urgent need for secure, reliable synchronization Adtran’s new OSA 3300 Super HP and OSA 3350 Super ePRC+ meet the need for ...

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 ...
