171 Yb + optical clock with 2.2 × 10 − 18 systematic uncertainty and absolute frequency measurements
A full evaluation of the uncertainty budget for the ytterbium ion optical clock at the National Physical Laboratory (NPL) was performed on the electric octupole (E3) 2 S 1 / 2 → 2 F 7 / 2 transition. The total systematic frequency shift was measured with a fractional standard systematic uncertainty...
