Dynamics of a flux qubit coupled with a quantized electromagnetic mode of a lossy cavity

The dynamics of a rf-SQUID qubit placed within a 1-D lossy resonant cavity is reported. Initially preparing the combined system in a state with no more than one excitation, the effects of loss mechanisms can be carefully analyzed, for different values of the cavity quality factor Q. The results here discussed demonstrate the possibility of controlling these phenomena in such a way to be able to observe 'coherent' Rabi oscillations and the periodically generation of factorized and entangled states (with a priori known characteristics). The importance of these results in the general context of quantum communications is carefully discussed as well as some technical detail necessary for the experimental feasibility of my theoretical scheme.
