Scientists in Germany have unveiled that the world’s most precise mobile atomic clock is so accurate that it will be off by ...

The first-ever deployment of a quantum optical atomic clock on an underwater autonomous submarine has been successfully ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...

MIT researchers double the accuracy of optical atomic clocks by reducing quantum noise with an innovative laser technique.

Most of the atomic clocks in the world - fewer than 500 in total - are housed at standards institutes and used to keep time ...

MIT researchers unlock a hidden effect to stabilize optical clocks, which may help advance the search for elusive phenomena ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...
