Talk Title: "Bulk Locality and Quantum Error Correction in AdS/CFT," by Daniel Harlow (Harvard)

Abstract:

Perhaps the most basic mystery of AdS/CFT is how a theory in d dimensions can be equivalent to a theory in d+1 (or higher) dimensions.  In this talk I will present several algebraic paradoxes that sharpen this puzzle, and then explain how they can be resolved via the theory of quantum error correction.  In their resolution it is essential that one side is gravitational while the other is not.  This leads to a new interpretation of AdS/CFT as a quantum error correcting code, with the algebra of bulk effective field theory being realized only on a protected subspace of states.  I will present an exactly soluble discrete model of the correspondence that illustrates these ideas explicitly.
