A quantum cataloguing scheme to identify any unknown quantized cavity field state using the atom interference is proposed. The scheme consists of sending a two-level state atom through two cavities, with Bragg and Raman-Nath regimes, respectively. We inveterate the atom interference from the second cavity to achieve different interference patterns which depend on the photons statistics.

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.
