Gravity and Entanglement

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 quantum 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.
