Entanglement and gravity in three dimensions

Quantum entanglement has played a central role in recent advances in diverse fields of study. In particular, in the context of quantum gravity and holographic duality, there are hints that entanglement is intimately related to the emergence and connectedness of geometry.

Gravity in three dimensions is particularly simple, so it offers a rich and powerful laboratory for exploring these ideas. I'll describe how entanglement entropies in states dual to solutions of pure 3D gravity can be computed extremely simply and purely algebraically, and then show that wormholes joining multiple exterior regions can be built from CFT states with a very simple local, bipartite entanglement structure.
