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 ...

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

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

BRAUNSCHWEIG, Germany — Time measurement is entering a new era. The next generation of atomic clocks uses laser light instead of microwaves to track time, oscillating about 100,000 times faster than ...

The new research controls the noise in atomic frequency to double the precision of atomic clocks for a more accurate time.

There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location, Internet timing,... To explore deep space, we'll need better clocks.

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even rewrite ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks work, ...
