Superposition States in Cavities Fed by Injected Atoms

Abstract

We study the possibility of producing disentangled states in the 3aynes- Cummings model when the input field is a superposition of two Fock states, jM) and jM + I), and the atom is initially in a superposition of its two stationary states. In the case of large M, we show that 3aynes-Cummings interaction provides quantum state swapping between the two qubits (atom and field).
