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." ...

For years, physicists have been trying to design clocks that can measure tiny durations of time with extreme precision. Quantum clocks, in particular, have pushed the boundaries by using the strange ...

Here’s what you’ll learn when you read this story: Timekeeping has evolved greatly during humanity’s short time on Earth, and that legacy of metrological innovation is far from over. A new study from ...

Why have just one technological breakthrough when you can have two at the same time? The Royal Navy has installed for the first time a quantum clock into its XV Excalibur robotic submarine for ...

Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...
