Optimal Control for Quantum Technology with NV-Centers in Diamond — •Matthias Müller — Peter-Grünberg-Institute of Quantum Control (PGI-8), Forschungszentrum Jülich GmbH

Diamond-based 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 use of QOC for NV-centers in diamond [1], the CRAB algorithm for Optimal Control [2], the optimal-control software QuOCS [3] and report on recent applications toward quantum sensing and quantum computing [4,5,6].
