Functional inequalities in quantum information theory
… to study the asymptotic properties of certain quantum Markovian evolutions. In this thesis, we study various extensions and problems arising from the specific noncommutative nature of such processes. The first logarithmic Sobolev inequality to be proved, due to Gross, was for the Ornstein …

Detection and estimation of quantum channel capacities
This thesis investigates the subject of quantum channel capacities and is composed of two parts. 1. Detecting positive quantum capacities of quantum channels Determining whether a noisy quantum channel can be used to reliably transmit qubits at a non-zero rate is a challenging problem, since it …
