A Tutorial on Floquet Codes
summary
Shows that toric‑code behavior arises from repeated two-body measurements by cycling condensations of color‑code anyons, concretely the red x → green y → blue z sequence that swaps e and m after two rounds. Uses the color‑code parent, measures edge hopping operators, tracks detector cells in a 3D space‑time picture, and demonstrates error correction with a matching decoder and circuit‑level simulations reporting about a 0.3% threshold, all consistent with anyon condensation.
