For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized ...

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental ...

Cutting-edge atomic clocks may soon reveal a strange possibility: time itself behaving like a quantum object, existing in ...

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 ...

Physicists like to measure things, and they like those measurements to be as precise as possible. That means working at unfathomably small scales, where distances are much smaller than even the ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...
