Design automation software tools for Topological Quantum Error Correction

Qiskit quantum error correction framework

Simulation and visualization of quantum error correcting codes

✅ 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.
