In a series of papers, we have discussed the dynamics of an open system. These describe the general situation when time irreversibility is involved . If the system lacks memory, the evolution describes a semi group, and the general form of the corresponding infinitesimal generator was given by Gorini, Kossakowski and Sudarshan for finite dimensional state spaces  and for bounded operators by Lindblad . Here we assume the evolution to be of this type. The general theory we present is based on the work  and the references there in. Here I summarize the theory in Sec. 2 and apply it to a communication situation in See. 3. This is modelled on the quantum scattering theory . The response of a quantum optical system has earlier been formulated in terms of input and output states, see e.g.  and ; for a discussion see .
