EUROPE — Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn’t lose or ...

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 ...

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 ...

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 ...

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 ...

A new version of the periodic table of elements has predicted hundreds of highly charged ions that could be used to create the next generation of optical atomic clocks. The periodic table, first ...
