How Atomic Clocks Keep Perfect Time

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 ...

Using atomic nuclei could allow scientists to read time more precisely than ever – what this research could mean for future clocks

Atomic clocks exploit the properties of atoms to create incredibly precise 'ticks.' Nate Phillips, NIST Most clocks, from ...

The most precise clock ever built ticks closer to reality

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

Bringing quantum time into the lab—a single clock can run young and old at once

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...
