Abstract: A interaction model of multi-photon process in the "multi-coupled-atom-cavity" system is constructed. In terms of the cavity quantum electrodynamics, the properties of quantum information transfer in the process of coupled atoms interacting with cavity fields are studied, and the effect of the coupling between atoms on the quantum information transfer is analyzed. It is found that quantum information can be transferred back and forth or be preserved between the cavity fields and atoms in certain time period. The dipole interaction between atoms leads to the quantum entanglement information partially transferred and partially preserved.
