论文摘要
我们考虑了两个两分部分的费米金系统纯状态之间的本地操作和经典交流（LOCC）歧视的问题。我们表明，与量子系统的情况相反，对于费米子系统，通常不可能通过LOCC测量来实现理想的状态歧视性能。另一方面，我们表明，在最大纠缠状态下由两个费米子模式制成的辅助系统是通过LOCC测量获得理想性能的足够的额外资源。当对两种状态的制备概率受到干扰，并得出歧视误差的紧密结合时，研究了理想结果的稳定性。
We consider the problem of local operations and classical communication (LOCC) discrimination between two bipartite pure states of fermionic systems. We show that, contrary to the case of quantum systems, for fermionic systems it is generally not possible to achieve the ideal state discrimination performances through LOCC measurements. On the other hand, we show that an ancillary system made of two fermionic modes in a maximally entangled state is a sufficient additional resource to attain the ideal performances via LOCC measurements. The stability of the ideal results is studied when the probability of preparation of the two states is perturbed, and a tight bound on the discrimination error is derived.
