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, ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized laser, where atoms work in concert rather than independently. Publishing ...

Physicists are preparing to test whether time itself can exist in a quantum superposition, using ultra-sensitive atomic clocks capable of detecting minute fluctuations. The proposed experiment could ...

For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new ...

About a decade ago, physicists put forward a theory that proposes how to investigate the quantum nature of time. It can be possible for clocks to experience superposition, where two different states ...

(THE CONVERSATION) Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a ...

You can buy all kinds of conventional clocks that have hands and numbers for easy reading. Or, like [Fabio Ricci], you could build yourself something a little more esoteric, like this neat shadow ...

Trapped ions are versatile platforms used for quantum computing and ultra-precise timekeeping. New results now show that combining these capabilities can reveal a deeper layer of physical reality: ...
