Thomas Galley

Thomas Galley's picture

Research Interests

I work in quantum foundations and am interested in two main areas: the structure of operational theories, and relational quantum mechanics.

- In GPTs I use representation theoretic tools to study and classify transitive state spaces.

-I study quantum reference frames, and am interested in the issue of transforming between perspectives in setups such as Wigner's friend experiments.
