Encoding quantum information in the spins of electrons or holes confined in semiconductor quantum dots is an extremely promising technology, due to long coherence times, inherent gate-voltage tunability, and compatibility with industrial foundry fabrication. As these quantum devices are scaled up in linear and two-dimensional arrays, the density of gate electrodes can lead to more and more operational complexity. In this talk, I will present our advances in implementing fast, high-fidelity, and simultaneous qubit readout as well as in the automated tuning, loading and calibration of gate-voltage controlled arrays of quantum dots. I will also showcase new techniques such as real-time fast feedback that enable "online" closed-loop control of quantum systems. Lastly, I will describe added functionality due to cross-connections between the fields of quantum information and more fundamental condensed matter physics, in the context of hybrid superconductor-semiconductor materials.
