Evolutionary BP+OSD Decoding for Low-Latency Quantum Error Correction
A new evolutionary belief propagation (EBP) decoder optimized via differential evolution (DE) algorithm is proposed to address high complexity and latency in quantum error correction. The EBP+OSD structure uses gradient-free DE for end-to-end optimization and a multi-objective selection rule to reduce OSD activation. Tests on surface codes and QLDPC codes show superior decoding performance.
