Entanglement, decoherence and correlations in a strongly driven Jaynes-Cummings system / F. Casagrande, A. Lulli. - In: OPEN SYSTEMS & INFORMATION DYNAMICS. - ISSN 1230-1612. - 13:4(2006), pp. 437-444.
Abstract:
We consider the resonant interaction of a cavity mode with a two-level atom that is
driven by a coherent field while it crosses the cavity. Starting from the cavity field in a coherent state, we show that the state of the system can reach the maximum entanglement after a unitary evolution for long enough interaction times. Also we illustrate how the generation of cavity field superposition states can allow, in the open system dynamics, the observation of their decoherence in atomic correlation measurements, for any initial cavity field state, and even under the combined
effects of dissipation, thermal noise, and atomic pumping.
