| 摘 要： | 为了解决生成量子稳定子码的码字时需先找出种子生成器的问题,将寻找种子生成器转化为解线性方程组及线性空间中向量组线性相关和线性无关问题,提出了快速判决法、排序查找法和求解方程组方法来验证找到的算子是否为合法的种子生成器.将稳定子与种子生成器同时标准化可以快速得到量子稳定子码的编码电路.给出了稳定子码种子生成器总数和编码电路所需要的2-qubit和1-qubit门数量.该方法既能用于同时包含Ⅰ型和Ⅱ型生成元的量子稳定子码,又能用于仅含Ⅰ型生成元的量子稳定子码,得到的种子生成器仅含X算子,故编码电路简单.

| Abstract: | In order to generate the quantum error-correcting codes based on the stabilizer it is needed to generate seed generator at first.The problem of finding seed generators is transformed into the problems of determining linear independence or linear dependence of vectors and finding the solutions of equation.Quick determinant method,sort and find method and solve equations method are presented to verify the validity of the operators.Through standardizing the generator of the stabilizer and the seed generators a... |
