Let p be a prime of the form \(p=mt+1\), where integers \(t\ge 1, m\ge 2\) and \(R_m=\mathbb {F}_p[u]/\langle u^m-1\rangle .\) Thus, \(R_m\) is a finite commutative non-chain ring. For a given unit \(\lambda \in R_m\), we study \(\lambda \)-constacyclic codes of length n over \(R_m\). The necessary and sufficient conditions for these codes to contain their Euclidean duals are determined. As an application from dual-containing \(\lambda \)-constacyclic codes over \(R_m\), for \(m=2,3,4\), we obtain many new quantum codes that improve on the known existing quantum codes.

来自非链环上的稳态代码的新量子代码
令p为\(p = mt + 1 \)形式的素数,其中整数\(t \ ge 1,m \ ge 2 \)和\(R_m = \ mathbb {F} _p [u] / \ langle u ^ m-1 \ rangle。\)因此,\(R_m \)是有限的可交换非链环。对于给定的单位\(\ lambda \ in R_m \),我们研究\(\ lambda \)-在\(R_m \)上长度为n的常数循环码。确定这些代码包含其欧几里得对偶的必要和充分条件。作为来自双重包含\(\ lambda \)- \(R_m \)上的常量代码的应用程序,对于\(m = 2,3,4 \),我们获得了许多新的量子代码,它们在已知的现有量子代码上有所改进。
