Error Correction Zoo
@eczoo.bsky.social
Repository and taxonomy of encodings to robustly store and process classical or quantum information. Recent results and highlights. 1000 codes and counting! https://errorcorrectionzoo.org/ https://discord.gg/gg3pJZNYxQ
And if you have an EC or QEC paper, consider getting an agent to push to the Zoo!
Victor V. Albert@vva.bsky.social · 2w agoWe're at a strange, specific moment. Takes range from "publications are dead by fall" to "I tried LLMs in November, they were bad." If you have an LLM-assisted paper, take full responsibility as usual. Do everything: arXiv, GitHub, website, and integrate with databases if appropriate.
After extensive experiments with AI agents, the [72,36,16] extremal code remains elusive—and possibly more intractable than we expected. This isn’t your average Erdős puzzle; it’s full-stack math + compute. We’re opening the search to the community: take a shot. valbert4.github.io/selfdual_site/

Big update: the EC Zoo is now a handbook. It spans codes, sphere packings, lattices, designs, groups, and phases of matter. Extensively checked, but not perfect—feedback very welcome: arxiv.org/abs/2606.11484
Handbook of Error-Correcting Codes

The forward-looking Oratomic time-efficient architecture claims to "potentially enable runtimes of 10 days for ECC–256 with ≈26,000 qubits, and 97 days for RSA–2048 with ≈102,000." This is based on stitching together several gadgets and plausibly assuming they can work together on an atom platform.

Peter Shor: we haven't found many new quantum algorithms, in part, because we need larger quantum devices for testing our heuristics. He gives several examples of algorithms that were discovered computationally, including turbo codes, @fermilab.bsky.social quantum symposium by the SQMS center.

Quote by W. Wesley Peterson in a 1962 Scientific American article somewhat rings true today, except with "quantum" everywhere.
"For decades, experimental progress on QEC lagged far behind theory, but this is starting to change."
John Preskill@preskill.bsky.social · 10mo agoWhen and how will quantum computing broadly benefit humanity? Despite exhilarating recent progress, we still don’t know. Here my friend Jens Eisert and I assess the current status and the challenges ahead. arxiv.org/abs/2510.19928
