Quantum interference is one of the most interesting phenomena in the field of quantum communications. So it is important to investigate properties of quantum interference for several quantum processes. This paper clarifies some properties as a quantum channel of the Jaynes-Cummings model (JCM) which is one of attractive models to generate quantum interference. When input states are assumed to be pure state, output states are approximately treated as a pure state. It is called Gea-Banacloche effect. This effect is not available in the small photon number region. It is, however, shown that the quantum interference can be observed in the measurement of the quadrature amplitudes at the special condition even if the output state is a mixed state. As a result, we conclude that it has still potentialty on possibility of the application of quantum interference effect.
