Vlatko Vedral

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.

An Argument Against Quantizing Spacetime

Someone witty once said: “It’s hard finding a black cat in a dark room” and then added sarcastically:” …especially when there is no black cat”. This metaphor of a *non-existent black cat in a dark room* is frequently used by atheists to argue against religion (God being the cat), but here I want to argue against the view that space and time need to be quantized…

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…
