论文摘要
提出了量子动力学半群的放松速率的通用约束的猜想。结果表明，它适用于几个有趣的半群，例如从适当的显微镜模型中衍生出的弱耦合极限的Unital半群和半群。此外，数值分析支持拟议的猜想。该猜想具有几个重要的含义：它允许为量子通道光谱提供通用约束，并提供必要的条件来决定给定的通道是否与马尔可夫进化一致。
A conjecture for the universal constraints for relaxation rates of a quantum dynamical semigroup is proposed. It is shown that it holds for several interesting classes of semigroups, e.g. unital semigroups and semigroups derived in the weak coupling limit from the proper microscopic model. Moreover, proposed conjecture is supported by numerical analysis. This conjecture has several important implications: it allows to provide universal constraints for spectra of quantum channels and provides necessary condition to decide whether a given channel is consistent with Markovian evolution.
