We broaden the study of circulant Quantum Markov Semigroups (QMS). First, we introduce the notions of -circulant GKSL generator and -circulant QMS from the circulant case, corresponding to , to an arbitrary finite group . Second, we show that each -circulant GKSL generator has a block-diagonal representation , where is a -circulant matrix determined by some . Denoting by the subgroup of generated by the support of , we prove that has its own block-diagonal matrix representation where is an irreducible -circulant matrix and is the index of in . Finally, we exploit such block representations to characterize the structure, steady states, and asymptotic evolution of -circulant QMSs.

我们拓宽了循环量子马尔可夫半群 (QMS) 的研究。首先,我们引入以下概念-循环GKSL发生器和- 来自循环案例的循环 QMS,对应于, 到任意有限群. 其次,我们证明每个-循环 GKSL 生成器具有块对角线表示, 在哪里是一个-由某些人确定的循环矩阵. 表示为的子群由支持产生, 我们证明有自己的分块对角矩阵表示在哪里是不可约的-循环矩阵和是指数在. 最后,我们利用这种块表示来表征结构、稳态和渐近演化- 循环质量管理体系。
