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 ...

Physicists are quietly rewriting one of the most basic units in science, using a new generation of optical clocks that can keep time so precisely they barely lose a beat over the age of the universe.

Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

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 ...

(Adam Gault/Photographer's Choice RF/Getty Images) Researchers in China have created one of the most precise clocks ever made ...

Chinese scientists create clock so precise it could redefine second - Optical clock measures time using light emitted by ...

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.

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 ...

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 ...
