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. https://research-explorer.ista.ac.at/download/18653/18662/2024_PhysicalReviewApplied_Hickie.pdf application/pdfno https://creativecommons.org/licenses/by/4.0/ American Physical Society2024 eng 2331-7019 00137915590000310.1103/PhysRevApplied.22.064026 226 Hickie, J., Van Straaten, B., Fedele, F., Jirovec, D., Ballabio, A., Chrastina, D., … Ares, N.
