Abstract

Control of quantum dynamics with high fidelity in the presence of noise is one of the requirements of quantum technologies. Here we develop a variational control approach for open quantum systems which is completely based on dynamics (process matrix) and is independent of initial conditions. We obtain a set of equations for optimal control of an open quantum system. We solve these equations iteratively for the particular case of simulating a dynamics in a preset time.
