FM 13: Open and Complex Quantum Systems I

FM 13.1: Invited Talk

Montag, 23. September 2019, 14:00–14:30, 3042

Quantum Information Concepts in Open Systems — •Bassano Vacchini — Dipartimento di Fisica Aldo Pontremoli, Università degli Studi di Milano, Via Celoria 16, I-20133 Milan, Italy — INFN, Sezione di Milano, Via Celoria 16, I-20133 Milan, Italy

The talk is aimed at providing an introduction to the foundations of open system theory in the light of quantum information concepts. We will briefly introduce the basic assumptions and general concepts of the theory, such as complete positivity and quantum dynamical map, relevant to the description of dissipation and decoherence effects in quantum mechanics. We will consider some of the main methods for the treatment of open system dynamics, pointing to the relevance of correlations such as entanglement and discord. We will further mention recent developments for the definition and treatment of non-Markovian dynamics as well as quantum thermodynamical systems, where quantum information notions appear to play an important role. Relevant open questions and possibly promising future research directions will be finally mentioned.
