| Abstract: | The fidelities of quantum states in the interaction system of an atom with a single-mode light field via two-photon processes are studied, by considering the second-order correction of atomic scattering. The influence of the nonlinear correction term, the two photon frequency detuning and the initial mean-photon number on the fidelities of quantum states is discussed. |
