Efficient Approximate Degenerate Ordered Statistics Decoding for Quantum Codes via Reliable Subset Reduction
Ching-Feng Kung, Kao-Yueh Kuo, Ching-Yi Lai
Efficient and scalable decoding of quantum codes is essential for high-performance quantum error correction. In this work, we introduce Reliable Subset Reduction (RSR), a reliabili…
Degenerate quantum erasure decoding
Kao-Yueh Kuo, Yingkai Ouyang
Erasures are the primary type of errors in physical systems dominated by leakage errors. While quantum error correction (QEC) using stabilizer codes can combat erasure errors, it r…
Streaming Belief Propagation on Mixed-Alphabet Tanner Graphs for Practical Quantum Memory
Kao-Yueh Kuo, Ching-Yi Lai
Reliable quantum memory under circuit-level noise requires decoders that can process syndrome information continuously and at a rate comparable to its generation. In practical quan…
