We construct qubit stabilizer codes with parameters $[[81, 0, 20]]$ and $[[94, 0, 22]]$ for the first time. We use symplectic self-dual additive codes over $\mathbb{F}_4$ built by modifying the adjacency matrices of suitable metacirculant graphs found by a randomized search procedure.

翻译：我们第一次用参数[[81,0,20]]$和[94,0,22]]$来构建qubit稳定器代码。我们使用优于$\mathbb{F ⁇ 4$(美元)的间歇性自我添加编码,通过修改随机搜索程序找到的合适成色图的相邻矩阵。
