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...

In our world of (noisy) data, error correction is everywhere, as Mary Wootters eloquently explains.

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

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:
arxiv.org/abs/2408.15925

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 $...
