In closing of #qec2025, we have put up our 1000th code -- the [[8,3,2]] surface code on a cube (aka the Landahl plucky code)! It is a non-CSS code different from the smallest interesting color code. Stabilizer generators are X, Y, or Z strings on the faces. errorcorrectionzoo.org/c/cubic_surf...
\([[8,3,2]]\) Surface code on a cube
An [[8,3,2]] twist-defect surface code whose qubits lie on the vertices of a cube. It is obtained by three-coloring the faces of a cube and placing X, Y, and Z stabilizer generators on each pair of fa...

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

behind theory, but this is starting to change."

We are now at 999 codes. What should be our 1000th? If we pick yours, we will feature you in a post about the code.

Comment, reply, message, and spread the word.

We mourn the loss of one of the founders of the QEC (Knill-Laflamme) conditions and one of the first to write down the five qubit code (aka the Laflamme code). errorcorrectionzoo.org/c/stab_5_1_3
Raymond Laflamme 1960-2025. A great scientist, renowned for his pioneering contributions to quantum error correction. A great leader, founding director of the Institute for Quantum Computing. A great colleague and teacher whose legacy continues to inspire us.

Ted Yoder summarised the onslaught of qLDPC logic papers (for fixed architectures) from IBM (and others).

I’ve read most/some of these papers but had a few gaps remaining in my understanding before today …

Huge congratulations to my amazing student Yeyuan Chen (+co-author Zihan Zhang of OSU advised by Zeyu Guo) for being awarded the STOC 2025 Best Student Paper Award! Their monumental result proves that explicit Reed-Solomon codes can correct more errors than previously known:

Explicit Folded Reed-Solomon and Multiplicity Codes Achieve Relaxed Generalized Singleton Bounds
In this paper, we prove that explicit FRS codes and multiplicity codes achieve relaxed generalized Singleton bounds for list size $L\ge1.$ Specifically, we show the following: (1) FRS code of length $...
