By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

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, ...

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 ...

Have you ever looked at a clock and thought, “This could be so much more than just a way to tell time”? Imagine a timepiece that doubles as a modern art installation, a glowing hexagonal masterpiece ...
