Optimal control and selectivity of qubits in contact with a structured environment
Quentin Ansel, Jonas Fischer, Dominique Sugny +1
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 z…
Fundamental Bounds on Qubit Reset
Daniel Basilewitsch, Jonas Fischer, Daniel M. Reich +2
Qubit reset is a basic prerequisite for operating quantum devices, requiring the export of entropy. The fastest and most accurate way to reset a qubit is obtained by coupling the q…
Time-optimal purification of a qubit in contact with a structured environment
Jonas Fischer, Daniel Basilewitsch, Christiane P. Koch +1
We investigate the time-optimal control of the purification of a qubit interacting with a structured environment, consisting of a strongly coupled two-level defect in interaction w…
