There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

Physicists are quietly rewriting one of the most basic units in science, using a new generation of optical clocks that can keep time so precisely they barely lose a beat over the age of the universe.

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 ...

DARPA has announced a new initiative called the Robust Optical Clock Network (ROCkN) program, which will look to develop a practical, super-accurate optical atomic clock that is robust and small ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

WASHINGTON — In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...
