In this talk I will explain recent progress in quantum gravity using quantum information theory and AdS/CFT correspondence. AdS/CFT correspondence tells us that quantum gravity on Anti de Sitter space is equivalent to QFT on the spacetime boundary. The crucial observation here is that various interesting gravity observables in AdS/CFT can be nicely analyzed by quantum information theoretic observables of the boundary QFT. One of the most important quantity is the entanglement entropy, which corresponds to the area of extremal …
