Abstract

We introduce surface ZZZY codes, a novel family of quantum error-correcting codes designed for asymmetric channels. Derived from standard surface codes through tailored modification of generators, ZZZY codes can be decoded by the minimum weight perfect matching (MWPM) algorithm with a suitable pre-processing phase. The resulting decoder exploits the information provided by the modified generators without introducing additional complexity. ZZZY codes demonstrate a significant performance advantage over surface codes when increasing the channel asymmetry, while maintaining the same correction capability over depolarizing channel.

非对称信道的量子编码：ZZZY 表面码

我们介绍了表面 ZZZY 码，这是一种专为非对称信道设计的新型量子纠错码系列。ZZZY 码是通过对生成器进行定制修改而从标准表面码中衍生出来的，它可以通过最小权重完全匹配（MWPM）算法和适当的预处理阶段进行解码。由此产生的解码器可利用修改后的生成器提供的信息，而不会带来额外的复杂性。当信道不对称程度增加时，ZZZY 码与表面码相比具有显著的性能优势，同时在去极化信道上保持相同的校正能力。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
