Single-photon state in a driven Jaynes-Cummings system - art. no. 010301

We present a practical scheme of preparing a temporally stationary single-p hoton-trapped state. A special dynamics at two-photon resonance in the coup led atom-cavity system, where a two-level atom is driven by a classical fie ld, is investigated for this purpose. It is found that significant atomic d amping is required, rather than avoided, to establish the one-photon Fock s tate. We analytically derive the optimal conditions in the large detuning l imit.
