Optical lattice clocks, the pinnacle of timekeeping, are key to exploring the relationship between quantum mechanics and ...

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 ...

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

The invention – called the optical lattice clock – is a thousand times more accurate than cesium atomic clocks used for international timekeeping and is a contender for redefining how long a ...
