We quantified how much closer OpenAI's improvement over MRRW brings us to GV lower bound: at most 2%. Gain over MRRW: at most ~1%.

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/

Assuming these estimates hold up, the number of physical qubits already made in the lab and the number required for running utility-scale algorithms would be, for the first time, in the same ballpark. Given Google's parallel paper and move to scope out atom platforms, people are starting to notice.

On the hardware side, serious players will be looking to create scalable foundry-level tools for atom-based devices like those for chip-based hardware. One thing Team Atoms always has going for them: Nature made all atoms identical!

Error Correction Zoo @eczoo.bsky.social · 01/04/2026
Many gadgets have yet to be fully optimized for the QLDPC + neutral atom combination. This optimization is crucial, as atom-based platforms are natively slower than chip-based platforms by orders of magnitude.

Error Correction Zoo @eczoo.bsky.social · 01/04/2026
Shor's algorithm has lots of moving parts, and runtimes are improving every year. The non-geometrically local connectivity of neutral atoms enables further reductions using QLDPC codes. There is plenty of room at the bottom here: QLDPC is the bleeding edge.

Error Correction Zoo @eczoo.bsky.social · 01/04/2026
The paper punts the LLM-assisted QEC codes used for the time-efficient estimate to future work. We are left to speculate why they were omitted. Perhaps time pressure, perhaps novel constructions too hard to explain for now.

Error Correction Zoo @eczoo.bsky.social · 01/04/2026
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.

Turbo codes were shown experimentally to nearly achieve Shannon capacity, and information theorists didn't believe that a telecom engineer was able to solve this longstanding problem.

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.

"Third, implementation of real-time QEC with sufficiently high throughput and latency may favor using simple decoders (e.g., cellular automata), which may not be compatible with the most resource-efficient QEC codes."
