This repository implements decoders for Quantum Error Correction, focusing on the repetition code with both ideal and noisy ancilla measurements.
- Written in Stim (fast stabilizer circuit simulator) and PyMatching (MWPM decoder).
- Generates decoding graphs for Minimum Weight Perfect Matching (MWPM) decoding.
- Calculates logical error rates for various code distances.
- Determines the error threshold by analysing performance under different noise models.
