The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. In ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

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 ...

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 ...

The geospatial sector, and the wider community, relies on precise timekeeping based on microwave atomic clocks. Is that about ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

As well as being useful for creating an optical ion clock, this multi-ion capability could also be exploited to create quantum-computing architectures based on multiple trapped ions. And because the ...
