A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium ...

Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...

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 ...

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, ...

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental ...

Scientists have taken a major leap towards making an entirely new type of clock — one based on tiny shifts in energy in an atomic nucleus. In principle, a nuclear clock could be even more precise than ...

After 78 years, the Doomsday Clock has been set closer than it has ever been. As a global society, we are now only 89 seconds to midnight after scientists moved the clock’s hand one second closer to ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by ...

The Department of Defense has awarded quantum technology firm Infleqtion an $11 million contract to help it speed up the development of its atomic timing technology. Atomic clocks are one of the most ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...
