超越整环稳定子码

Beyond Integral-Domain Stabilizer Codes

Lane G. Gunderman

AI总结:

针对合数局部维度量子系统缺乏稳定子码理论的问题,提出两种将已知稳定子码转换为有效合数维度码的构造,并讨论逻辑编码与数量,拓展了辛空间理解。

摘要:

量子纠错码旨在保护量子系统中的信息,以实现容错量子计算。最普遍的方法——稳定子码,已在多种系统中得到充分发展;然而,系统能级数为合数的情形在很大程度上一直被回避。这种相对缺失源于分析此类系统所需的底层环论工具。在此,我们探索合数局部维度的量子稳定子码,给出一对构造,用于将已知稳定子码转化为适用于合数局部维度的有效码。此外,还讨论了关于逻辑编码及可能数量的评述。本工作阐述了处理合数维度系统的核心方法,使某些系统的计算空间得以充分利用,并拓展了对所涉及辛空间的理解。

英文摘要:

Quantum error-correcting codes aim to protect information in quantum systems to enable fault-tolerant quantum computations. The most prevalent method, stabilizer codes, has been well developed for many varieties of systems, however, largely the case of composite number of levels in the system has been avoided. This relative absence is due to the underlying ring theoretic tools required for analyzing such systems. Here we explore composite local-dimension quantum stabilizer codes, providing a pair of constructions for transforming known stabilizer codes into valid ones for composite local-dimensions. In addition remarks on logical encodings and the counts possible are discussed. This work lays out central methods for working with composite dimensional systems, enabling full use of the computational space of some systems, and expanding the understanding of the symplectic spaces involved.
