The fidelity evolution of quantum state under the interaction of the binomial photon field and atomic Bose-Einstein condensate(BEC)are studied by full quantum theory. The influences of the interaction among atoms of BEC,the average atomic number of atomic BEC and the parameter of light field on the fidelity are investigated. The results indicate that the amplitude and oscillated period of fidelity of quantum information for the interaction system can be controlled by choosing the intensity of the interaction among atoms and the average atomic number on the ground state. And the change of the light parameter only plays a role on the fidelity effect. The higher fidelity can be obtainedby choosing suitable parameters.
