Terms: https://qubitwire.com/terms Sources: Google Quantum AI and Collaborators: Quantum error correction below the surface code threshold: https://www.nature.com/articles/s41586-024-08449-y Nature: Author correction to the surface-code memory paper: https://www.nature.com/articles/s41586-026-10559-8 The surface-code paper reports below-threshold quantum memories and discusses the further work needed for logical computation. Its April 2026 correction changes labels and keys in Figure 3a. This original worksheet does not reproduce the paper’s figures. The three questions are QubitWire’s reading aid, not a scoring system or a result reported by the paper. They help expose mismatched tasks and missing context before making a numerical comparison.
