Optimal control and selectivity of qubits in contact with a structured environment

Understand

We present a theoretical study of the optimal control of a qubit interacting with a structured environment.

• We consider a model system in which the bath is a bosonic reservoir at zero temperature and the qubit frequency is the only control parameter.
• Using optimal control techniques, we show the extent to which qubit population and relaxation effects can be manipulated.
• The reachable qubit states by a shaped control with a fixed maximum intensity are found numerically.
