QIAW02 - New trends at the intersection of quantum information theory, quantum groups and operator algebras

The talk provides an introduction to dynamical decoupling, an error mitigation procedure in quantum information theory that aims to stabilise open quantum systems undergoing decoherence. We look at some of the mathematical challenges, provide conditions as to when and how dynamical decoupling does or does not work in given quantum systems, what the resulting dynamics looks like and how close the idealised mathematical description is to physical reality. The talk is based on a series of joint papers with C. Arenz, D. Burgarth, P. Facchi and/or M. Fraas.
