Black holes as non-isometric codes

Abstract: The interior of an old black hole is encoded in the Hawking radiation. Thisseems to be the implication of recent computations of the Page curve. We takethis idea to its logical conclusion, modeling old black holes as quantum codesembedding a large number of degrees of freedom (the interior and semiclassicalradiation) into a smaller number (the stretched horizon and physicalradiation). I will prove that such codes exist, and discuss their novelproperties and what they can tell us about black holes. ​
