説明
The dynamics of a quantum dense coding process is formulated and exactly solved on the basis of a boson detector model previously used to study decoherence processes. When classical information encoded in entangled states is transmitted through a quantum mechanical communication channel, an environment exerts quantum noise causing decoherence and disentanglement. Shannon’s mutual information and error probability function are obtained explicitly as functions of time.
