Sparse Mamba Decoder for Quantum Error Correction: Efficient Defect-Centric Processing of Surface Code Syndromes
Researchers have developed a new neural decoder called the Sparse Mamba Decoder (SMD) designed for quantum error correction. This decoder efficiently processes only the active error events rather than the entire syndrome array, significantly reducing computational complexity. SMD demonstrates improved accuracy and drastically faster processing speeds compared to existing decoders across various benchmarks, including experimental data from Google Sycamore. AI
