Matrixvalued Tsirelson Correlations
Bipartite probabilistic correlations can be used to describe quantum behaviour in finiteinput, finiteoutput systems involving two parties (Alice and Bob). In recent years, there has been a lot of progress in separating the correlation sets corresponding to different models of quantum mechanics. In this talk, we’ll consider a matrixvalued generalization of these correlations, which can be thought of as partial measurements on Alice and Bob’s system. We will see how we can separate certain models using matrixvalued correlations in situations where the analogous separations for probabilistic correlation sets are not known. This is based on joint work with Li Gao and Marius Junge.

Geometry and decay estimates in quantum information theory
Decay estimates are central to several problems in quantum information
theory. In this talk we will consider dynamical systems on state spaces
and relate decay estimates to geometric properties of the generating
Lindblad operator. In this analysis we follow the work of Carlen and
Mass on entropy estimates and combine it with tools from noncommutative
geometry.
This is joint work with Li Gao, Haojian Li, and Nick LaRacuente.
