Quantum optimal control: Theoretical considerations and application — •Jonathan Zoller — Ulm university, Germany

We employ and compare different optimal control algorithms as the CRAB and Gradient methods. These algorithms require initial guess pulses which, in general, result in different final fidelities: we perform a statistical analysis of the final fidelity distribution and of the algorithm performances. We apply this analysis to two paradigmatic optimal control problems such as a state to state transfer of an atom in a double-well between states located in two different wells and the generation of optimal protocols for the manipulation of Nitrogen-vacancy center in diamond.
