Innovative optical atomic clock could combine single-ion accuracy with multi-ion stability

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could change the definition of the base unit second in the International System of Units (SI).

Optical atomic clock combines single-ion accuracy and multi-ion stability

This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with the improved stability of multi-ion operation. The new atomic species is also very well suited as a multi-qubit for quantum information, as the quantum states can be manipulated extremely precisely using laser radiation.
