Abstract
Dynamical quantum dense coding process is discussed on the basis of an exactly solvable boson detector model. A previous treatment is extended to include finite temperature effect. Time evolution of density matrices is completely determined. Moreover, a quantum mechanical communication channel matrix and Shannon's mutual information are obtained as functions of time. Quantum and thermal noise effects due to the fluctuating environment are discussed.
