A next-generation atomic clock that tops previous records for accuracy in clocks based on neutral atoms has been demonstrated. The new clock, based on thousands of strontium atoms trapped in grids of ...

Imagine a clock that will keep perfect time forever or a device that opens new dimensions into the study of quantum phenomena such as emergence and entanglement. Researchers have proposed a space-time ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

Let’s face it: most of us have trouble getting out of bed. Many times it’s because the alarm isn’t loud enough to rouse us from our viking dreams. [RimstarOrg]’s homeowner’s association won’t let him ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...
