局域隐态的纠缠

Entanglement of Local Hidden States

Matteo Fadel, Manuel Gessner

摘要:

操纵准则是违反排除用局部隐藏状态(LHS)模型描述观测到的测量统计的可能性的条件。当现有数据不允许排除任意LHS模型时,仍然可以排除具有特定可分性结构的LHS模型。在这里,我们推导出实验可行的标准,把定量界的多体纠缠的LHS。我们的研究结果表明,可分离态可能包含隐藏的纠缠,可以通过对另一个系统的测量来解锁,即使两个系统之间没有转向是可能的。

英文摘要:

Steering criteria are conditions whose violation excludes the possibility of describing the observed measurement statistics with local hidden state (LHS) models. When the available data do not allow to exclude arbitrary LHS models, it may still be possible to exclude LHS models with a specific separability structure. Here, we derive experimentally feasible criteria that put quantitative bounds on the multipartite entanglement of LHS. Our results reveal that separable states may contain hidden entanglement that can be unlocked by measurements on another system, even if no steering between the two systems is possible.
