Gravity and Entanglement

Tuesday, October 13, 2015

Professor Mark van Raamsdonk of the University of British Columbia gives the Stanford Physics and Applied Physics Colloquium on October 13, 2015.

The AdS/CFT correspondence from string theory provides a quantum theory of gravity in which spacetime and gravitational physics emerge from an ordinary non-gravitational system with many degrees of freedom. In this talk, I will explain how quantum entanglement between these degrees of freedom is crucial for the emergence of a classical spacetime, and describe progress in understanding how spacetime dynamics (gravitation) arises from the physics of quantum entanglement.
