摘要
文章研究了有限域 $ F_{q^{2}} $ 上长为 $ (q^{4}-1)/8 $ 的负循环 Bose-Chaudhuri-Hocquenghem(BCH) 码,其中 q 为奇素数幂且 $ q \equiv 1 \pmod{4} $;给出了厄米特对偶包含负循环 BCH 码的最大设计距离,并确定了它们的维数;利用厄米特构造法,得到了新的参数良好的量子码。

Abstract
This paper studies negacyclic Bose-Chaudhuri-Hocquenghem (BCH) codes over the finite field $ F_{q^{2}} $ of length $ (q^{4}-1)/8 $, where q is an odd prime power and $ q \equiv 1 \pmod{4} $; the maximum designed distance of Hermitian dual-containing negacyclic BCH codes is given and the dimension of these codes is determined; a new class of quantum codes with good parameters is constructed using the Hermitian construction.
Keywords
