Scaling up the number of atoms or ions in optical atomic clocks enables better precision, but this is often accompanied by interactions that limit the accuracy. Here, the authors propose and discuss using a three dimensional Coulomb crystal of one thousand Sn2+ ions as an optical atomic clock with both high precision and high accuracy.
