Martianus Frederic Ezerman, Somphong Jitman, San Ling, Dmitrii V. Pasechnik

摘要:

非对称量子纠错码(AQC)可以通过为更频繁的错误类型提供更好的纠错来提供优于其对称对应物的一些优势。通过去除$\F_{q}$线性要求以及对所使用的内积类型的限制,扩展了$q$元AQC的公知CSS构造。建议的建设被称为CSS样的建设,并利用对嵌套子域线性码下的欧几里德,跟踪欧几里德,厄米特,跟踪厄米特内积。在建立了一定的理论基础后,构造了性能最好的类CSS AQC。结合经典码对的嵌套构造和线性规划,我们找到了许多最优的、性能良好的$q$ -ary CSS类$q \in {2,3,4,5,7,8,9}$码,在许多情况下,去除$\F_{q}$ -线性和使用替代内积,我们得到的纯AQC比单纯依赖标准CSS构造的AQC具有更好的参数.

英文摘要:

Asymmetric quantum error-correcting codes (AQCs) may offer some advantage over their symmetric counterparts by providing better error-correction for the more frequent error types. The well-known CSS construction of $q$-ary AQCs is extended by removing the $\F_{q}$-linearity requirement as well as the limitation on the type of inner product used. The proposed constructions are called CSS-like constructions and utilize pairs of nested subfield linear codes under one of the Euclidean, trace Euclidean, Hermitian, and trace Hermitian inner products. After establishing some theoretical foundations, best-performing CSS-like AQCs are constructed. Combining some constructions of nested pairs of classical codes and linear programming, many optimal and good pure $q$-ary CSS-like codes for $q \in {2,3,4,5,7,8,9}$ up to reasonable lengths are found. In many instances, removing the $\F_{q}$-linearity and using alternative inner products give us pure AQCs with improved parameters than relying solely on the standard CSS construction.
