Quantum Dynamical Mutual Entropy Based on AOW Entropy
Kyouhei Ohmura, Noboru Watanabe · Open Systems & Information Dynamics · 2019
The classical dynamical mutual entropy measures the average of information content going through a channel. Classical Markovian sources are important in communication theory since they constitute reasonable models for languages. In this paper, we define the quantum dynamical mutual entropy through quantum Markov chains, and we calculate it for several simple models.
