The AdS/CFT correspondence is often quoted as providing a complete theory of quantum gravity in asymptotically AdS space, but precise probes of the bulk have been limited so far. Can the dictionary be expanded to describe a more detailed set of bulk observables, in particular including those behind horizons? Recent work on black hole physics has emphasized the extent to which we do not have a satisfactory answer to this question. Attempts to understand this have begun to involve a variety of techniques from quantum information theory, in particular entanglement monogamy, error correction, and computational complexity.
