Interplay of decoherence and relaxation in a two-level system interacting with an infinite-temperature reservoir
Interplay of decoherence and relaxation in a two-level system interacting with an infinite-temperature reservoir
We study the time evolution of a single qubit in contact with a bath, within the framework of projection operator methods. Employing the so-called modified Redfield theory, which also treats energy conserving interactions nonperturbatively, we are able to study the regime beyond the scope of the ordinary approach. Reduced equations …
