Group seminar
Theoretical quantum science and technology
(Every term)
Group members will present and discuss their latest progress and results and give tutorial talks. Some talks will also be given by (external) visitors.
Students are always very welcome, credits can be obtained by a presenting something of interest (e.g., a research paper).
Comments are always welcome at (teaching@mkliesch.eu).
Time and place: Fridays 10:30h, either in the seminar room 25.32.03.51 or in the “Hilbtertraum” 25.32.03.48.
Topics
Quantum many-body physics,
Quantum information theory,
Simulations of complex quantum systems,
Characterization and validation of quantum computing components,
applied math, and
machine learning in quantum physics.
