H. Moyacessa et A. Vidiellabarranco, ON THE INTERACTION OF 2-LEVEL ATOMS WITH SUPERPOSITIONS OF COHERENT STATES OF LIGHT, J. mod. opt., 42(7), 1995, pp. 1547-1552
In this paper we study the decoherence process occurring when a field
prepared in quantum superpositions of coherent states (Schrodinger cat
s) interacts with a two-level atom in the framework of the Jaynes-Cumm
ings model. We emphasize the influence of the relative phase in the in
itial superposition state on the purity of the field during the evolut
ion.
