论文摘要
当系统强烈耦合到环境并长时间与环境相互作用时，量子进化中的非马克维亚效应就会出现。为了在主方程式中包括内存效果，通常会合并时间局部发电机或内存内核。但是，事实证明，非马克维亚的进化具有永恒的负反矫正速率，这是由马尔可夫半群的简单混合物引起的。此外，一个人可以拥有多达$（d-1）^2 $的总费率总计$ d^2-1 $总计，量子进化仍然是合法的。
Non-Markovian effects in quantum evolution appear when the system is strongly coupled to the environment and interacts with it for long periods of time. To include memory effects in the master equations, one usually incorporates time-local generators or memory kernels. However, it turns out that non-Markovian evolution with eternally negative decoherence rates arises from a simple mixture of Markovian semigroups. Moreover, one can have as many as $(d-1)^2$ always negative rates out of $d^2-1$ total, and the quantum evolution is still legitimate.
