Quantum information theory is used to study the dynamics of the two-photon Jaynes_Cumming model with atomic motions. The quantum mechanics channels representing the atomic states change in the model are given. The quantum mutual entropy and the atomic reduction entropy are derived. The atomic motions and the field mode structures On the mutual entropy of quantum and the relationship between the “on” and “off” states and the degree of atom entanglement with the quantum mechanics channel.The results show that the characteristics of the quantum mechanics channel strongly depend on the atomic motion, the field mode structure and the entanglement of the atom and the field .
