The fidelities of quantum states of system in Jaynes-Cummings model containing atomic motion

The fidelities of quantum states of system in Jaynes Cummings model containing atomic motion under action of coherent field are studied. The influence of atomic motion and the field mode structure on the fidelities of quantum states of system in different atomic initial states is discussed. The result indicates that both the atomic motion and the field mode structure can modulate the fidelities of quantum states in the system of interaction.
