qecsim is a Python 3 package for simulating quantum error correction using stabilizer 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.
