A talk by Daniel Harlow at the Workshop on Computational Complexity and High Energy Physics, hosted July 31 to August 2, 2017 by the Joint Center for Quantum Information and Computer Science at the University of Maryland.

Abstract: In this talk I review the new connection between quantum error correction and holographic duality. Using the simplest holographic code, the three qutrit code, I illustrate holographic phenomena such as radial locality and the Ryu-Takayanagi formula, and I also sketch how these results can be used to give a rather general proof of the old conjecture that there are no global symmetries in quantum gravity.
