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

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

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

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, ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

Testbed submarine XV Excalibur went to sea with Infleqtion’s quantum optical atomic clock on board – the first time such a ...

On Sunday, Nov. 2, we head back into Standard Time and say goodbye to Daylight Saving Time until March 8, 2026.
