Closed-Loop Control with Tailored Benchmarking Protocols — •Matthias Müller — Forschungszentrum Jülich

Quantum technology is a fast-emerging field with both scientific and technological importance. The performance relies on unique features like superposition and entanglement and depends on sophisticated mechanisms of control to perform the desired tasks. Quantum Optimal Control (QOC) has proven to be a powerful tool to accomplish this task. I will give a brief overview on the CRAB algorithm for QOC [1] and the optimal-control software QuOCS [2], and then talk about recent work on closed-loop control [3,4,5] for one- and two-qubit gates.
