摘要
我们引入了一个用于构造不可区分费米子粒子子系统完全正映射的框架。在此情形下，初始全局态总是关联的，且无法将系统与环境区分开来。尽管如此，对于某些仅存在交换这种非经典关联的态集合，仍可获得算子求和表示下的约化映射。

9 pages, 2 figures. In this new version we eliminated a section with a mistaken definition of mutual information for indistinguishable particles, which was not relevant for the main argument of our paper
