Abstract

The evolution of fidelity of quantum information in pair atoms of entanglement state interacting with coherent light field was investigated. The expression of fidelity of quantum information in J-C model with many-photon transition was written out. Time-evolution of fidelity of quantum information in J-C model with one-photon transition or two-photon transition was compared.
