关于量子和经典BCH码

On Quantum and Classical BCH Codes

Salah A. Aly, Andreas Klappenecker, Pradeep Kiran Sarvepalli

摘要:

经典BCH码包含其(欧几里德或厄米特)对偶码,可以用来构造量子稳定子码;这种对应关系研究了这种码的性质。证明了长度为n的BCH码只有当其设计距离d=O(sqrt(n))时才能包含其对偶码,并在狭义码的情况下证明了相反的结果.此外,尺寸的狭义BCH码与小的设计距离是完全确定的,因此,他们的最小距离的界限得到改善。这些结果使得根据量子BCH码的设计参数来确定量子BCH码的参数成为可能。

英文摘要:

Classical BCH codes that contain their (Euclidean or Hermitian) dual codes can be used to construct quantum stabilizer codes; this correspondence studies the properties of such codes. It is shown that a BCH code of length n can contain its dual code only if its designed distance d=O(sqrt(n)), and the converse is proved in the case of narrow-sense codes. Furthermore, the dimension of narrow-sense BCH codes with small design distance is completely determined, and - consequently - the bounds on their minimum distance are improved. These results make it possible to determine the parameters of quantum BCH codes in terms of their design parameters.
