The Lorentz Center organizes the public lecture ‘Contextuality: At the Borders of Paradox’ by Professor Samson Abramsky

Contextuality: At the Borders of Paradox
Quantum mechanics famously contains many troubling and highly counterintuitive features, which may even seem to be paradoxical. At the same time, these features lie at the heart of the promise of quantum technologies to revolutionize our world by performing information processing tasks better than any classical computer can - the *quantum advantage*.

We shall argue that quantum mechanics, and in particular the key feature of quantum contextuality, lives at the borders of paradox — and that this is an exciting place to be! The talk will be illustrated by examples of visual paradoxes due to Maurits Escher and Roger Penrose; and by examples drawn from elementary logic and the information world around us.

Our world *is* contextual; and we are beginning to learn how to work with contextuality, and to exploit its quasi-paradoxical features.

This lecture is part of the Lorentz Center workshop ‘Logical Aspects of Quantum Information’, which will take place in Leiden from 30 July to 3 August 2018. 

The topic of this workshop is the emerging interaction between quantum information and logic in computer science. The aim is to bring together researchers, both junior and senior, from different communities in an effort to communicate state-of-the-art advances, strengthen the existing interaction and create new bridges between the different areas.
