摘要：

基于Z2pm上的二阶广义割圆构造一类新型的量子可同步码，此类纠错码具有最优的纠正信息块同步错误的能力，其可同步能力总是其上界2pm。此外，这类码字对由量子噪声引起的比特错误和相位错误也具有一定的纠错能力。最后，给出一些具有最优块可同步能力的量子可同步码。

关键词: 量子可同步码, 循环码, 对偶包含码, 分圆陪集

Abstract:

A new family of quantum synchronizable codes from generalized cyclotomy of order two over Z2pm are constructed whose synchronization capabilities always reach the upper bound 2pm. In addition, this kind of codes also have ability to correct bit errors and phase errors caused by quantum noise. Finally, some quantum synchronizable codes with optimal capabilities of block synchronization are presented.

Key words: quantum synchronizable codes, cyclic codes, dual-containing codes, cyclotomic cosets
