- Towards Recovering a Holographic Bulk from Entanglement

The AdS/CFT correspondence provides a remarkably useful tool

for asking questions in quantum gravity, as it formulates a theory of

quantum gravity in terms of an ordinary non-gravitational quantum field

theory. Fruitfully exploiting this correspondence therefore requires

understanding how to translate the language of CFT into gravity; a key

insight that has emerged over the past decade is that the entanglement

structure of the CFT must be intimately tied to the emergence of the

gravitational dual (when a classical geometric picture even exists). In

my talk, I'll review what is currently known about this emergence

(so-called bulk reconstruction), and then discuss some recent results on

precisely how the entanglement of the CFT fixes the geometry on the

gravitational side. I'll conclude with some open directions, notably

how the result I'll present is amenable to incorporating quantum

corrections.
