A short introduction to Quantum Channels: Characterization and Methods (I)

Date and Time: Thursday 16th of October 2025. 12pm.
Place: Laboratorio de Física Computacional, Facultad de Ciencias (Ground Floor, next to the Foucault pendulum)

Speaker: Prof. Michalis Skotiniotis (QTCG-UGR)

Abstract: This series of lectures tackles the dynamics of open quantum systems from the point of view of Quantum Channels. These are Completely Positive, Trace Preserving (CPTP) maps acting on the space of linear operators. The first lecture concerns the derivation of the Gorini, Kossakowski, Sudarshan, Lindblad (GKSL) Master Equation from an entirely mathematical point of view using functional analysis. The second lecture concerns the characterization of CPTP maps and particularly their mathematical characterization in terms of the Matrix representation, Kraus representation, Stinespring Representation and Choi-Jamiolkowski representation. The third and final lecture will tackle the question of how to obtain the Kraus representation of a CPTP map given a master equation of GKSL form and present some examples.

This seminar is organized by the Quantum Thermodynamics and Computation Group (QTCG) at the University of Granada. They warmly invite students, researchers, and the wider university community to participate in this new seminar series.
