The world’s first nuclear clock is on the horizon It would be 1,000 times more accurate than today’s atomic timekeepers ...

In an optical atomic clock, atoms are irradiated by laser light. If the laser has the correct frequency, the atoms change their quantum-mechanical state.

Institutions Time frame: 1 February 2024 - 31 January 2025 Institution search supports local language names. , Home Articles Optical atomic clock interrogation using an integrated spiral cavity laser ...

Atomic scientists moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine and other factors underlying the risks of global ...

A recent breakthrough has paved the way for timekeeping even more precise than the measurements performed by atomic clocks.

On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick ...

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wa… ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate.

This laser system could also sync up the nuclear “ticks” with the atomic clock, allowing the atomic clock to stay on track with nuclear time.

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...
