Abstract

This talk reviews known connections between quantum gravity and quantum information, including (a) entanglement and Hawking radiation, (b) teleportation and black hole evaporation, (c) bit creation during inflation, and (d) the holographic principle. After the review, I will present a theory of quantum gravity based on quantum computation that provides explicit models for all these phenomena within a framework that allows quantitative calculations.
