Revisiting quantum feedback control: disentangling the feedback‐induced phase from the corresponding amplitude

Barkemeyer, Kisa ; Finsterhölzl, Regina ; Knorr, Andreas ; Carmele, Alexander (2019-10-11)

Coherent time‐delayed feedback allows the control of a quantum system and its partial stabilization against noise and decoherence. The crucial and externally accessible parameters in such control setups are the round‐trip‐induced delay time τ and the frequencies ω of the involved optical transitions which are typically controllable via global parameters like temperature, bias, or strain. They i...
