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

At this year's LASER World of Photonics (2025), in Munich, Germany, Toptica Photonics introduced to the market what the Munich-based company describes as "the first commercially available optical ...

Phase noise of quantum-enhanced feedback oscillators. Spectra of the output phase quadrature for four types of quantum noise-limited oscillators. Red shows the Schawlow-Townes spectrum of an ...

It’s clock time again on Hackaday, this time with a lovely laser-cut biretrograde clock by [PaulH175] over on Instructables. If you’ve never heard of a ‘biretrograde clock,’ well, we hadn’t either.

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

An NIST physicist holds the newly modified ion trap for the aluminum ion clock. By modifying the trap, the aluminum ion and its magnesium ion partner could 'tick' unperturbed. Optical atomic clocks ...

To measure time, you need a constant rhythm. For eons, the regular movements of the sun and moon have set the pace for all of life on Earth. But over millennia, humans have sought and found more ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...
