Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by ...

What we’re able to do is divide the same length of time into smaller and smaller units, Adam Kaufman described, speaking to how entanglement sharpens the tick of optical atomic clocks. That one line ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

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 ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

Rising precision demands and GPS/GNSS vulnerabilities are driving the urgent need for secure, reliable synchronization Adtran’s new OSA 3300 Super HP and OSA 3350 Super ePRC+ meet the need for ...

It's Memorial Day, Short Wavers. This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend ...

Physicists are exploring thorium-229’s unique properties to create a nuclear clock so precise it could detect the faintest hints of dark matter. Recent measurement advances may allow scientists to ...
