neural-decoder

Open-source QEC decoders: Pathfinder — a direction-aware neural surface-code decoder (real-time-budget Triton kernel) whose multi-seed ensemble lowers logical error below the prior open-source GNN at operational noise rates — plus a kernel-grounded, MLE-anchored latency–LER benchmark for circuit-level qLDPC (bivariate-bicycle) codes.

PyTorch implementation of the Graph Structure-Aware Error Correction Code Transformer (GSA-ECCT) for neural soft decoding of linear error-correcting codes.
