标题： Fully Parallelized BP Decoding for Quantum LDPC Codes Can Outperform BP-OSD

摘要： 在本工作中，我们提出了一种仅基于置信传播（BP）的轻量级解码器，并引入了一种受经典Chase解码启发的推测性后处理策略。 我们的方法通过 BP振荡统计识别不可靠位，生成一组修改后的测试模式，并使用低迭代BP并行解码它们。 我们证明了我们的方法可以达到与BP-OSD相当或更好的逻辑错误率，但针对多种二元自行车码具有更低的延迟，显著降低了解码复杂度。 显示英文摘要

摘要： In this work, we propose a lightweight decoder based solely on belief-propagation (BP), augmented with a speculative post-processing strategy inspired by classical Chase decoding. Our method identifies unreliable bits via BP oscillation statistics, generates a set of modified test patterns, and decodes them in parallel using low-iteration BP. We demonstrate that our approach can achieve logical error rates comparable to or even better than BP-OSD, but has lower latency over its parallelization for a variety of bivariate bicycle codes, which significantly reduces decoding complexity.
