I am the Professor of Quantum Information Theory at the University of Oxford, as well as for the Centre for Quantum Technologies at the National University of Singapore. I spend a lot of my time thinking about what quantum mechanics actually means, and how it affects everything and everyone around us.
Refrigeration with Indefinite Causal Orders on a Cloud Quantum Computer
We demonstrate non-classical cooling on the IBMq cloud quantum computer. We implement a recently proposed refrigeration protocol which relies upon…
Indefinite Causal Orders from Superpositions in Time
Treating the time of an event as a quantum variable, we derive a scheme in which superpositions in time are…
How quantum theory says we can never see a complete picture of reality
Schrödinger’s cat is only the start of quantum weirdness, it leads us to strange worlds where personalities split and time does not exist.
I’m building a machine that breaks the rules of reality
We thought only fools messed with the cast-iron laws of thermodynamics, but quantum trickery is rewriting the rulebook.
