If you have a question about this talk, please contact Jamie Vicary.

In this talk I will discuss my work on operational approaches to Quantum Theory and General Relativity. The basic element of an operational approach is an operation. This can be visualised as a box with settings (e.g. knobs we adjust) and outcomes (e.g. lights that flash, detectors that click, ...). Furthermore, these boxes can be wired together to form a circuit. I will discuss the operator tensor approach to formulating Quantum Theory in these terms and also talk briefly about how to formulate General Relativity in such a way. The ultimate goal of this approach is to find a theory of Quantum Gravity. If time allows, I will discuss some of the unique challenges that a theory of Quantum Gravity raises for computer science.
