Quantum Entanglement and Holographic Spacetime

Speaker:  Tadashi Takayanagi  Institute:  Kyoto University 
Abstract:  In this colloquium, I would like to review a recently developed new interpreta tion of gravitational spacetime in terms of quantum entanglement. The idea of holography in string theory provides a simple geometric computation of entangl ement entropy. This generalizes the wellknown BekensteinHawking formula of b lack hoe entropy and strongly suggests that a gravitational spacetime consists of many bits of quantum entanglement. This suggests an interpretation of surf aces in gravitational spacetimes as quantum circuits. I would like to explain these recent developments.
