论文摘要
我们构建一个动态图，该图是不可分离的，并且也不显示信息回流（如痕量标准量词衡量）。它是针对正在进行非可逆动力学的QUTRIT系统制定的。这提供了一个证据表明，基于信息回流的缺乏和阳性划分的两个定义对于一般的非不可逆转动态图而言不合格
We construct a dynamical map which is not positive divisible and does not present information backflow either (as measured by trace norm quantifiers). It is formulated for a qutrit system undergoing noninvertible dynamics. This provides an evidence that the two definitions of quantum Markovianity based on absence of information backflow and positive divisibility are nonequivalent for general noninvertible dynamical maps
