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 ...

At the heart of this change is a new kind of atomic clock that uses light ... one indium ion that acts as the "clock" and three ytterbium ions that cool it down. These ions interact to form ...

This development marks a significant step toward deployable, low-power atomic clock systems that can be ... amplified using a Ytterbium (Yb)-doped yttrium aluminum garnet (YAG) bulk crystal ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

Whether you find yourself glancing at a clock on the wall or checking your phone, the time you constantly see is the product of a meticulous system upheld by the world’s timekeepers. In the U.S., a ...

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 ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency ...

An atomic clock research team from the National Time Service Center of the Chinese Academy of Sciences has proposed and implemented a compact optical clock based on quantum interference enhanced ...

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 ...

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall ...
