The 2015 Andrew Chamblin Memorial Colloquium

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.
Entanglement and Spacetime
