Highly charged ion used in a new class of optical clock

An optical clock based on a highly charged ion has been demonstrated for the first time. The results pave the way for extremely accurate highly charged-ion clocks that could have applications in both timekeeping and the further exploration of fundamental physics.

This is a summary of: King, S. A. et al. An optical atomic clock based on a highly charged ion. Nature 611, 43–47 (2022).
