Integer Linear Programming Decoder for Abelian and Non-Abelian Topological Codes
A new arXiv preprint introduces an integer linear programming (ILP) decoder designed for both Abelian and non-Abelian topological quantum error-correcting codes. The authors formulate decoding as an integer linear program and apply it to topological code families including non-Abelian ones.

Within two years, this ILP decoder could become a reference implementation for benchmarking heuristic decoders on small non-Abelian topological codes.
Non-Abelian codes lack mature fast decoders; an exact ILP solution, though likely not scalable, can establish optimal thresholds on small instances, and the community often adopts such solvers as ground truth for decoder comparisons.
