Decoding correlated errors in quantum LDPC codes

Year: 2026

Type: article

Abstract: Quantum low-density parity-check codes are promising but still miss feasible and reliable general decoding methods. Here, the authors present a decoding graph transformation which results into an accurate, fast, hardware-friendly decoding method for quantum LDPC codes that handles realistic correlated noise while maintaining very low logical error rates.
