Beyond Quantum Markovian Semigroups

Explore the intricacies of open quantum systems in this comprehensive lecture by Prof. Dariusz Chruscinski from Nicolaus Copernicus University. Delve into the limitations of Schroedinger unitary evolution when describing systems coupled to environments, leading to decoherence and dissipation. Gain a foundational understanding of Markovian semigroups and the crucial concept of complete positivity in quantum information theory. Examine the challenges of non-Markovian evolution, illustrated through simple physical models. Investigate the natural connection between quantum stochastic processes and the properties of Markovianity and classicality. This colloquium, presented at the Center for Theoretical Physics of the Polish Academy of Sciences, offers valuable insights into the complexities of quantum systems beyond traditional Markovian frameworks.
