Breakthrough could pave the way for next-generation GPS in drones, smartphones and self-driving cars, scientists say.

The challenge here is to shrink these systems down enough, so they actually fit in applications where they'd be most useful.

Conversely, if you stick to a regular sleep pattern, when we “fall back” on Nov. 2, 2025, you will gain an hour of sleep. Heading to sleep at 11 p.m. and waking at 6 a.m. will give you one more hour ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

A solid-state nuclear clock has a great potential to become a robust and portable timing device that is highly precise.

That way, frequency combs act like a bridge between the atomic transition at an optical frequency and the clock signal at a radio frequency that is electronically detectable for counting the ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

They may also set themselves according to atomic clocks. They even adjust when we travel into different time zones if they are taken out of airplane mode upon arrival. A radio-controlled clock ...

"Fortunately, our microcomb chips can act as a bridge between the optical signals of the atomic clock and the radio frequencies used to count the atomic clock's oscillations. Moreover, the minimal ...

We normally think of atomic clocks as the gold standard in timekeeping. The very definition of a second — in modern times, at least — is 9,192,631,770 periods of the radiation corresponding to ...

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping.

"Fortunately, our microcomb chips can act as a bridge between the optical signals of the atomic clock and the radio frequencies used to count the atomic clock's oscillations. Moreover, the minimal ...
