利用二次剩余集设计量子稳定子码

Design of Quantum Stabilizer Codes From Quadratic Residues Sets

Yixuan Xie, Jinhong Yuan, Qifu, Sun

摘要:

我们提出了两种类型,即类型I和类型II,量子稳定子码使用的二次剩余集的素数模的形式$p=4n\pm1$。所提出的I型稳定器码具有循环结构和码长$N=p$。它们是基于由二次剩余集得到的幂等多项式生成的多权循环矩阵而构造的。所提出的II型稳定子码具有准循环(QC)结构和码长$N=pk$,其中$k$是二次剩余集的大小。它们是基于由原矩阵和循环置换矩阵导出的结构稀疏图码构造的。利用所提出的方法,我们设计了丰富的循环和准循环量子稳定子码的可变码长。我们展示了如何交换约束(也称为辛内积约束)的量子码可以满足每一个建议的建设方法。我们还分析了第一类稳定码的维数和距离以及第二类稳定码的维数。对于循环量子稳定子码,我们证明了它们满足文献中已有的距离界。

英文摘要:

We propose two types, namely Type-I and Type-II, quantum stabilizer codes using quadratic residue sets of prime modulus given by the form $p=4n\pm1$. The proposed Type-I stabilizer codes are of cyclic structure and code length $N=p$. They are constructed based on multi-weight circulant matrix generated from idempotent polynomial, which is obtained from a quadratic residue set. The proposed Type-II stabilizer codes are of quasi-cyclic (QC) structure and code length $N=pk$, where $k$ is the size of a quadratic residue set. They are constructed based on structured sparse-graphs codes derived from proto-matrix and circulant permutation matrix. With the proposed methods, we design rich classes of cyclic and quasi-cyclic quantum stabilizer codes with variable code length. We show how the commutative constraint (also referred to as the Symplectic Inner Product constraint) for quantum codes can be satisfied for each proposed construction method. We also analyze both the dimension and distance for Type-I stabilizer codes and the dimension of Type-II stabilizer codes. For the cyclic quantum stabilizer codes, we show that they meet the existing distance bounds in literature.
