Tuning arrays with rays: Physics-informed tuning of quantum dot charge states. (arXiv:2209.03837v1 [cond-mat.mes-hall])

Quantum computers based on gate-defined quantum dots (QDs) are expected to
scale. However, as the number of qubits increases, the burden of manually
calibrating these systems becomes unreasonable and autonomous tuning must be
used. There have been a range of recent demonstrations of automated tuning of
various QD parameters such as coarse gate ranges, global state topology (e.g.
single QD, double QD), charge, and tunnel coupling with a variety of methods.
Here, we demonstrate an intuitive, reliable, and data-efficient set …
