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, ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to microwaves, like conventional atomic clocks. The accuracy of these clocks ...

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