Quote by W. Wesley Peterson in a 1962 Scientific American article somewhat rings true today, except with "quantum" everywhere.

Peter Shor receives a small gift on the 30th anniversary of his QEC paper at #QEC2025.

Artist Stewart Smith cools down the participant "qubits" to prepare for decoding the surface code at the QEC Choir interactive art exhibit at @qec2025 at the @yaleqi.bsky.social.

Tutorials begin at QEC2025 at @yaleqi.bsky.social. Here is an artistic rendition of some famous codes at the Google Quantum AI tutorial.

We’re excited to share updates ensuring the long-term sustainability of the EC Zoo. To continue delivering great content and improving your experience, we’re introducing a new subscription-based model. Check out our website for more detailed information!

Ben Reichardt summarizes leading platforms at the annual experimental talk @qip2025.bsky.social, this time given by a theorist.

All parents are listed below the hierarchy, also with tags to their notable ancestors. E.g., the Shor code is also a special case of a surface code (on the projective plane) and a qudit [[9,1,3]] code.

Each level of the hierarchy contains tags to certain "notable" codes that are ancestors of the code at that level. That way, we see a partial tree of notable ancestors. E.g., the Shor code is a CSS code, stabilizer code, concatenated code, qubit code, Hamiltonian code, etc.

Major update: The zoo is not just a repository, but also a taxonomy. Now, every code page has a visualization of the code's primary ancestors. 🧵

We're hitting a steady 1.1k+ visitors per day on average, with interesting patterns emerging. Here's to another year of beautiful results!

Last big peak at 3.2k must have been from the PR of the Google result, which we discussed several months before when it came out.

You can now BibTeX the thousands of references mentioned in the zoo!
