I am the Professor of Quantum Information Theory at the University of Oxford.
I spend a lot of my time thinking about what quantum mechanics actually means, and how it affects everything and everyone around us.

The Infamous Mod Square
Because everything in quantum physics behaves like a wave, the primary entities are given by what are known as amplitudes. Amplitudes can be thought of as propensities (to borrow a term from Aristotle) for a wave of one configuration to – later on – acquire another configuration.

What is life?
I know of at least three books with this title. The most famous one is, of course, by Erwin Schrödinger. If you haven’t read it, I really recommend it highly. It’s difficult to overstate its importance.
Spacetime and Memory
Despite the fact that the theory of relativity unified space and time into one entity called spacetime, many physicists (and philosophers and others) feel that time somehow holds a different status to space.
Do we really need a theory of everything?
Finding a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. But do we really need a theory of everything? That’s what I discussed in the final episode of the Great Mysteries of Physics podcast – hosted by Miriam Frankel, science editor at The Conversation, and supported by FQxI, the Foundational Questions Institute.
Pionic Entanglement in Femtoscopy: A Lesson in Interference and Indistinguishability
We present an analysis of recent experiments in femtoscopy by the STAR collaboration in terms of the protocol of entanglement…
Quantum Causal Inference with Extremely Light Touch
We consider the quantum version of inferring the causal relation between events. There has been recent progress towards identifying minimal…
