Time-dependent Schrieffer-Wolff-Lindblad perturbation theory: Measurement-induced dephasing and second-order Stark shift in dispersive readout
We develop a time-dependent Schrieffer-Wolff-Lindblad perturbation theory to study effective interactions for driven open quantum systems. The starting point of our analysis is a given Lindblad equation, based on which we obtain an effective (averaged) map that describes the renormalization of both the Hamiltonian and collapse operators due to the …
