Noise Contributions of the Strontium Lattice Clock

Caption

Noise contributions of the strontium lattice clock as a function of the number of atoms. The predicted total noise at suppressed frequency noise of the interrogation laser (green line) is confirmed by experimental data (green circles). The quantum projection noise (blue line) already dominates with few atoms.
