About
How can it be that a local quantum field theory in some number of spacetime dimensions can "fake" a local gravitational theory in a higher number of dimensions? How can the Ryu-Takayanagi Formula say that an entropy is equal to the expectation value of a local operator? Why do such things happen only in gravitational theories? In this talk I will explain how a new interpretation of the AdS/CFT correspondence as a quantum error correcting code provides satisfying answers to these questions, and more generally gives a natural way of generating simple models of the correspondence. No familiarity with AdS/CFT or quantum error correction is assumed, but the former would still be helpful. .
