Thomas Fraser, postdoc

Thomas is broadly interested in the intersection between information theory and group theory, especially in the context of multipartite quantum systems and quantum networks. He is currently working with Matthias Christandl from the Centre for the Mathematics of Quantum Theory to develop mathematical tools better to understand the structure of multipartite quantum states and tensors.

Thomas received his PhD from the University of Waterloo (Canada) in September 2023 under the supervision of Robert Spekkens while working at the Perimeter Institute for Theoretical Physics.

His thesis, titled "An estimation theoretic approach to quantum realizability problems", applied results from non-commutative optimization and group representation theory to characterize relationships between various covariant and spectral properties of quantum states.

Before that, Thomas received a master’s degree for developing combinatorial methods to study statistical correlations in causal networks and an undergraduate degree in Mathematical Physics, both from the University of Waterloo.

Thomas also often goes by just his first and middle initials: T.C. His office is located in the QMath group at Vibenshuset.
