我们调查现有的技术计算代码距离的经典代码,并将这些技术应用到一般的量子码。对于经典和量子LDPC码,我们还提出了一种新的链接簇技术。它降低了所有现有的确定性技术设计的代码与小的相对距离(包括所有已知的家庭的量子LDPC码)的复杂度指数,也超过了概率技术足够高的码率。
We survey the existing techniques for calculating code distances of classical codes and apply these techniques to generic quantum codes. For classical and quantum LDPC codes, we also present a new linked-cluster technique. It reduces complexity exponent of all existing deterministic techniques designed for codes with small relative distances (which include all known families of quantum LDPC codes), and also surpasses the probabilistic technique for sufficiently high code rates.
