Quantum Hidden Markov Chains. KU Leuven
In this thesis we study quantum mechanical processes with a Markovian character. We focus on matters that are of interest for quantum information theory. There are three main topics: capacity of memory channels, quantum correlations in bipartite systems and asymptotic entropy densities.Capacity is the amount of information that can reliably be sent through a communication channel. In practical applications, it is an important problem to ...
