I will present selected examples from our work encompassing multi-dot devices implemented in silicon structures and gallium-arsenide heterostructures, including active-learning algorithms that autonomously explore the charge stability diagram of capacitively coupled quantum dot arrays and spin rotations via real-time estimation of uncontrolled qubit parameters. These techniques will be important not only for the maturing of high-fidelity spin qubit devices via automated high-throughput device characterization, but also for the stabilization of operating parameters of quantum processors against environmental fluctuations.
