Entanglement and Spacetime

In this colloquium, I would like to review a recently developed new interpretation of gravitational spacetime in terms of quantum entanglement. The AdS/CFT correspondence in string theory provides a simple holographic computation of entanglement entropy. This generalizes the well-known "Entropy=Area relation" of Bekenstein-Hawking and strongly suggests that a gravitational spacetime consists of infinitely many bits of quantum entanglement. Indeed, an explicit realization of this idea is provided by so called tensor networks, which is a geometrical way to describe a given wave function in quantum many-body systems. I would like to explain these recent developments.



Note: The Andrew Chamblin Memorial Colloquium honors Andrew Chamblin of the University of Louisville, who passed away in 2006.

Refreshments will be served in CP 179 at 3:15 PM
