\([[8,3,2]]\) 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 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...

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.
