Hello!

I’m Vlatko,

I am the Professor of Quantum Information Science 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.

Crazy Quantum (Late-Night) Thoughts

The main obstacle to us making progress in quantum physics is the persistent (and misplaced) belief that quantum physics needs to be fixed.

What is a Q-Field?

I have frequently talked about the interpretation of quantum physics implying that “everything is a quantum wave”. Here I’d like to explain this a bit better and, more importantly, tell you about some problems with this picture of the universe.

Quantum Time and Cloning

I’ve recently been busy finalising a big review (300 plus references), together with Chiara Marletto, on Quantum Information methods applied to detecting…

Pyramids, Consciousness and the Limits of Science

I’ve recently watched a great simulation of how the human hearing mechanism operates. The air vibrations generated by some disturbance eventually reach our eardrum. The ensuing vibrations of the drum perturb a small bone called the hammer which starts to move up and down.

Quantum-information methods for quantum gravity laboratory-based tests

Quantum theory and general relativity are about one century old. At present, they are considered the best available explanations of physical reality, and they have been so far corroborated by all experiments realised so far. Nonetheless, the quest to unify them is still ongoing, with several yet untested proposals for a theory of quantum gravity. Here we review the nascent field of information-theoretic methods applied to designing tests of quantum gravity in the laboratory. This field emerges from the fruitful extension of quantum information theory methodologies beyond the domain of applicability of quantum theory itself, to cover gravity. We shall…

Quantum Mutual Information in Time

While the quantum mutual information is a fundamental measure of quantum information, it is only defined for spacelike-separated quantum systems. Such a limitation is not present in the theory of classical information, where the mutual information between two random variables is well-defined irrespective of whether or not the variables are separated in space or separated in time. Motivated by this disparity between the classical and quantum mutual information, we employ the pseudo-density matrix formalism to define a simple extension of quantum mutual information into the time domain. As in the spatial case, we show that such a notion of quantum…
