Quantum

I am interested in modelling, simulating, learning and controlling quantum systems with applications in quantum technologies, often related to spin dynamics. A particular interesting aspect of this is to learn physical laws of a system to enable to control it. Applications are focused on quantum spin networks, spintronics, magnetic resonance imaging and spectroscopy, and chemical synthesis.
