The black-hole/qubit correspondence: an up-to-date review

We give a review of the black-hole/qubit correspondence that incorporates not only the earlier results on black-hole entropy and entanglement measures, seven qubits and the Fano plane, wrapped branes as qubits and the attractor mechanism as a distillation procedure, but also newer material including error-correcting codes, Mermin squares, Freudenthal triples and four-qubit entanglement classification.
