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.

[Art] certainly lives up to his username. His Rubidium-standard atomic real-time clock is surely an example of hardware art. The substrate is a collection of point-to-point soldered perfboard modules.

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 ...

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 ...

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 ...

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 ...

Getty Images NPL's atomic clock, alongside clocks from around 80 labs worldwide, helps set Universal Coordinated Time (UTC), the official global time standard To pinpoint our exact location ...

"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 ...

For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of fundamental theories. But researchers at JILA ...

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