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

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But ...

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, it does ...

MIT physicists improved the stability of optical atomic clocks by reducing “quantum noise” — a fundamental measurement ...

Rising Research in Fundamental Physics Strontium optical lattice clocks are instrumental in testing Einstein’s theories, detecting gravitational waves, and studying fundamental constants, fueling ...

The universal need to be on time keeps everyone on the move, shaping society into a permanently well-oiled machine. Whether you find yourself glancing at a clock on the wall or checking your phone, ...

In a video demonstration, Microchip Technology’s chip-scale atomic clocks reveal their low phase noise and application ...

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 ...

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 standard — ...
