Are you passionate about equality, diversity and inclusion? Are you keen to make real positive change within MPLS and the University?
We are now inviting expressions of interest for our next cohort of MPLS ED&I Fellows. If you (or anyone you know) are passionate about ED&I and want to make positive change within our University, this could be for you.
One of the most important questions in theoretical physics is finding a theory of quantum gravity, which could help us address fundamental questions about our world, related to what is inside a black hole, or what is the origin of the universe. Several approaches have been developed over the past decades to tackle this problem, with string theory being a leading candidate due to its potential to unify the laws of physics.

On the (Local) Lifting Property
Tatiana Shulman
(University of Gothenburg)
Abstract
The (Local) Lifting Property ((L)LP) is introduced by Kirchberg and deals with lifting completely positive maps. We will discuss various examples, characterizations, and closure properties of the (L)LP and, if time permits, connections with some other lifting properties of C*-algebras. Joint work with Dominic Enders.

Quantum expanders from quantum groups.
Mike Brannan
(University of Waterloo)
Abstract
I will give a light introduction to the concept of a quantum expander, which is an analogue of an expander graph that arises in quantum information theory. Most examples of quantum expanders that appear in the quantum information literature are obtained by random matrix techniques. I will explain another, more algebraic approach to constructing quantum expanders, which is based on using actions and representations of discrete quantum groups with Kazhdan's property (T). This is joint work with Eric Culf (U Waterloo) and Matthijs Vernooij (TU Delft).
