Geometry and Entanglement

Julian Sonner
MIT

Is there a connection between entanglement and space-time geometry? Maldacena and Susskind proposed that entanglement is associated with Einstein-Rosen bridges, also called`non-traversable wormholes'. I will explain some of the arguments that have been proposed in favor of this relationship and then describe how the framework of holographic duality (or ‘AdS/CFT’) gives a controlled framework to investigate these ideas further. I will approach this question by constructing a holographically dual description of a maximally entangled pair of quarks, using the Schwinger effect at large 't Hooft coupling \lambda in N=4 supersymmetric Yang Mills theory. We shall see that there is indeed a wormhole associated with the dual of the the pair of quarks, when they are causally disconnected.
