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 ...

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

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 ...

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 ...

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 ...

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 — ...

Where and why tiny, portable, atomic clocks and their precision are needed. How atomic clocks are no longer room- or box-size arrangements. The size, power, and other metrics of a latest-generation ...

From sundials to atomic clocks, our understanding of time has become a lot more accurate as technological developments allowed us to measure it more precisely. Much more than helping us arrive on time ...
