建立了具有原子无退相干子代数的一致连续量子马尔可夫半群的结构，提供了将马尔可夫开放量子系统自然分解为其无噪声（无退相干）和不可约（遍历）分量的方法。这导致了不变状态结构的新特征和寻找无退相干子系统和子空间的新方法。给出了一些例子来说明这些结果。
The structure of uniformly continuous quantum Markov semigroups with atomic decoherence-free subalgebra is established providing a naturaldecomposition of a Markovian open quantum system into its noiseless (decoherence-free) and irreducible (ergodic) components. This leads to a new characterisation of the structure of invariant states and a new method for finding decoherence-free subsystems and subspaces. Examples are presented to illustrate these results.
