A technological innovation could revolutionize the precision of navigation systems. A tiny device, shaped like a comb, promises to deliver unparalleled accuracy in the field of positioning.

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 ...

Researchers have 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 ...

PLEASANTON, Calif.--(BUSINESS WIRE)--Vector Atomic has announced the launch of Evergreen-30, the world’s first fully integrated commercial optical clock. EG-30 introduces a new performance class to ...

Atomic clocks are at the leading edge of accuracy and precision and are essential for synchronisation of distributed critical infrastructure, position, navigation and timing, and scientific ...

Back in 2024, a joint collaboration of researchers from TU Wien in Austria and the National Institute of Standards and ...

Atomic timekeeping plays an essential role in modern infrastructure, from transportation to telecommunications to cloud computing. Billions of devices rely on the Global Navigation Satellite System ...

Unlike other atoms (left), ytterbium-173 (right) has a large nuclear spin and a strongly deformed nucleus whose strong fields interact with the electron shell. This turns forbidden quantum jumps into ...

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 ...
