Time-optimal synthesis of unitary transformations in a coupled fast and slow qubit system
Time-optimal synthesis of unitary transformations in a coupled fast and slow qubit system
In this paper, we study time-optimal control problems related to a system of two coupled qubits where the time scales involved in performing unitary transformations on each qubit are significantly different. In particular, we address the case where unitary transformations produced by evolutions of the coupling take a much longer …
