How Space and Time Could Be a Quantum Error-Correcting Code
A popular-science article, shared on Hacker News, on the conjecture that the AdS/CFT holographic correspondence behaves like a quantum error-correcting code, with bulk spacetime information redundantly encoded in boundary degrees of freedom. No abstract or technical content was supplied beyond the title, so the specific results discussed are not known here.
Why it matters: The holography\u2013QEC connection is mostly of conceptual interest, but it is where some code constructions (e.g. holographic tensor-network codes) originated, so it is worth knowing as background.
