A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

Tucked away in a vault in France is a weight made of platinum and iridium, diligently cared for by a team of highly trained specialists. Its sole purpose is to be, to sit and remain unchanging as the ...

Historically, JILA (a joint institute established by the National Institute of Standards and Technology [NIST] and the University of Colorado Boulder) has been a world leader in precision timekeeping ...

Atomic beam optical clocks offer continuous operation, simplified structure, and excellent short- to mid-term stability, making them promising candidates for next-generation optical flywheel clocks.

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But scientists at MIT and Harvard have just taken precision to an entirely new ...

The next generation of atomic clocks "ticks" at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

The challenge of creating the world’s most precise clock is that that even the slightest deviations limit the precision. Atomic clocks, which rely on the coherent evolution of atomic states, are the ...

Optical clocks represent the forefront of timekeeping and frequency metrology, exploiting ultranarrow electronic or vibrational transitions in atoms or molecules confined by optical potentials. By ...

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 ...
