Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical ...

A tomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

Microwave-based cesium atomic clocks have long been the gold standard for timekeeping and are an implementation of the ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

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 ...

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

For the first time, scientists have dated dinosaur eggs that lay buried in rock for millions of years, using a groundbreaking new ‘atomic clock for fossils’ method. During the Cretaceous period, Earth ...
