Abstract Here we consider the continuous pumping of a dissipative QED cavity and derive the time-dependent density operator of a cavity field prepared initially as a superposition of mesoscopic coherent states. The control of the coherence of this superposition is analyzed by considering the injection of a beam of two-level Rydberg atoms through the cavity. Our treatment is compared to other approaches.
