WebOct 1, 1995 · Markovian semigroups, however, provide only an approximate description of general quantum evolution. The main topic of our analysis are dynamical maps beyond this regime. Non-Markovian quantum evolution attracted a lot of attention in recent years and there is a vast literature dedicated to it. WebIt is demonstrated that similar universal properties hold for the detailed balance-obeying Kolmogorov generators obtained by applying superdecoherence to an ensemble of random Davies generators with imposed detailed balance condition. We introduce different ensembles of random Lindblad operators $\cal L$, which satisfy quantum detailed …
WebNote that the first evolution is always Markovian, i.e., the corresponding dynamical map is CP-divisible, as the hazard rate h (t) is always positive. On the contrary, the quantity μ (t) in the latter local master equation can typically become negative, which results in a non-Markovian dynamics. Notably, in both cases the evolution after the ... Webin the non-Markovian regime entanglement is possibly generated on a shorter time scale (∝t2) than in the Markovian regime (∝t). Moreover, although the singular coupling limit of non-Markovian dynamics yields Markovian ones, we show that the same limit does not lead from non-Markovian entanglement generation conditions to Markovian ones.
