โœฆ Synopsis


The quantum mutual entropy was introduced by one of the present authors in 1983 as a quantum extension of the Shannon mutual information. It has been used for several studies such as quantum information transmission in optical communication and quantum irreversible processes.

In this paper, a nonlinear channel for a quantum teleportation process is rigorously constructed and the quantum mutual entropy is applied to characterize the quantum teleportation processes of Bennett et al.
