基于纠缠辅助稳定器的形式,可以从任意经典线性码中得到纠缠辅助量子纠错码,极大地促进了量子编码理论的发展。本文构造了几个[公式:见文]长度[公式:见文]的任意纠缠辅助量子最大距离可分码族(EAQMDS),这些码族对最大纠缠态的最小距离[公式:见文]和个数[公式:见文]具有灵活的参数。大多数得到的EAQMDS编码的最小距离都大于文献中已有的编码。
Entanglement-assisted quantum error-correcting codes (EAQECCs) can be obtained from arbitrary classical linear codes based on the entanglement-assisted stabilizer formalism, which greatly promoted the development of quantum coding theory. In this paper, we construct several families of [Formula: see text]-ary entanglement-assisted quantum maximum-distance-separable (EAQMDS) codes of lengths [Formula: see text] with flexible parameters as to the minimum distance [Formula: see text] and the number [Formula: see text] of maximally entangled states. Most of the obtained EAQMDS codes have larger minimum distances than the codes available in the literature.
