Abstract

Quantum physics is notorious for confounding our intuitions, and predicts phenomena such as “spooky action at a distance” which cannot be accounted for in terms of classical physics, and yet which have been verified experimentally. We are now seeing the rise of quantum technologies, which aim to harness these phenomena to perform tasks which would be impossible classically. In this talk, we will explain some of these ideas without assuming any knowledge of quantum physics! We will see how the phenomenon of quantum contextuality leads us to the very borders of paradox, while enabling Alice and Bob to perform remarkable feats of cooperation which would not be possible without the use of quantum resources.
