Surface Code Python Packages

pymatching

PyMatching: A Python/C++ library for decoding quantum error correcting codes with minimum-weight perfect matching.

tesseract-decoder

Search-based decoder for quantum error correction (QEC) written in C++ and Python.

beliefmatching

An implementation of the belief-matching decoder

tqec

A design automation framework for Topological Quantum Error Correction.

panqec

Simulation and visualization of quantum error correcting codes

qsurface

✅ Python package for simulation and visualization of quantum error-correction on surface codes. The package provides the ability to inspect the error-correcting code during the decoding process, and tools to benchmark the decoder.

localuf

A Python package to simulate and visualise Union-Find-related decoders for the surface and repetition codes.

qtcodes

Qiskit Topological Codes
