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.

Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

An artist's rendition of the scandium nuclear clock: scientists used the X-ray pulses of the European XFEL to excite in the atomic nucleus of scandium the sort of processes that can generate a clock ...

In this case, the new clock uses an ion of aluminum linked to an ion of magnesium, forming what is known as a quantum logic clock. In this, the aluminum ion has a high-frequency, stable "tick." ...

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 ...

Established as a provider of high-end lasers and laser rack systems, Toptica has this week announced at LASER world of Photonics that is offering its first complete quantum technology solution: a ...

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 ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

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 ...
