Extended Data Fig. 4: Results of the simulations that vary the noise sources in the operation of the ZDT di erential spectroscopy operation.
From: Improved interspecies optical clock comparisons through differential spectroscopy
The top panel shows the contrast in the phase scan of the Al+ clock, and the bottom shows the Allan deviation plot for: when only the OLO noise is present (yellow line), when OLO and the magnetic field noise sources are present (orange line), and when OLO, magnetic field, and the fibre link noises are present (blue line). The green dashed line in the bottom panel indicates the QPN limit.
