  text: Charge sensing is a sensitive technique for probing quantum devices, of particular
    importance for spin-qubit readout. To achieve good readout sensitivities, the
    proximity of the charge sensor to the device to be measured is a necessity. However,
    this proximity also means that the operation of the device affects, in turn, the
    sensor tuning and ultimately the readout sensitivity. We present an approach for
    compensating for this crosstalk effect allowing for the gate voltages of the measured
    device to be swept in a 1-V × 1-V window while maintaining a sensor configuration
    chosen by a Bayesian optimizer. Our algorithm will hopefully be a major contribution
    to the suite of fully automated solutions required for the operation of large
    quantum device architectures.
