QEC-Playground
QEC-Playground is an open-source research and educational tool for topological quantum error correction. It supports circuit simulation with Pauli and erasure noise, multiple decoders including MWPM and Union-Find, and visualization of circuits, errors, and decoding results.
Originally started as a quantum-information course project in 2020, it grew into a tool for exploring QEC and debugging decoders. The source code and documentation are available on GitHub.
