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 ...

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 ...

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 Bulletin of the Atomic Scientists announced the symbolic Doomsday Clock will remain at 90 seconds to midnight for the second year in a row. The clock is the group's metaphorical depiction of how ...

What we’re able to do is divide the same length of time into smaller and smaller units, Adam Kaufman described, speaking to how entanglement sharpens the tick of optical atomic clocks. That one line ...
