The distance between the peaks is determined by the strength of interaction between a single photon in the resonator and electrons in the double quantum dot. This double peak feature disappears as strengths of energy and phase relaxation processes increases, recovering a simple classical condition for maximal current when the energy splitting between electronic states in the double quantum dot is equal to the photon energy. Then I discuss properties of electric current and photon field at finite bias across the DQD system and at zero microwave drive. I show that the low frequency current noise is affected by the coupling to photons and that the generated microwave field of the resonator may exhibit either photon bunching or antibunching.
