Recent research into quantum information theory has given us a much deeper understanding of quantum theory, and has led to the development of powerful new techniques and concepts that can be applied to other areas of physics. Tony Short research programme focuses on the foundational insights that can be gained from this approach. Three particular areas he is currently interested in are:
- Generalised non-signalling theories - We can view quantum theory in a general framework admitting other theories with similar (and even stronger) non-local properties. Comparing these theories may help us to understand why nature is quantum, or (if not) how to go beyond it to a deeper theory.
- Entanglement and the foundations of statistical mechanics - One of thebiggest challenges in understanding statistical mechanics is its use of probabilities, which appear to reflect subjective ignorance. However, probabilities can also arise as an objective consequence of quantum entanglement, and this approach naturally yields canonical mixed states and equilibration. Can it underpin, and go beyond, standard statistical mechanics?
- The continuum limits of quantum walks and quantum cellular automata - He plans to investigate how discrete quantum walks and quantum cellular automata relate to particle dynamics and quantum field theories in their continuum limits. Can quantum cellular automata simulate parts of the standard model, or perhaps even explain some of its structure?
