在前/后选择系综下，借助弱测量和双态矢量形式研究了纠缠和非定域性。除了EPR-Bohm实验之外，我们还回顾了Hardy和Chesshire Cat的实验，这些实验中纠缠的预选或后选态会产生奇怪的现象。然后，我们转向更奇特的现象，即“在独立的选择前和选择后的粒子集合之间出现了新的关联。这可以被视为对经典鸽子原理的量子违反”。
Entanglement and nonlocality are studied in the framework of pre-/postselected ensembles with the aid of weak measurements and the Two-StateVector Formalism. In addition to the EPR-Bohm experiment, we revisit the Hardy and Cheshire Cat experiments, whose entangled pre- or post-selected states give rise to curious phenomena. We then turn to even more peculiar phenomenon suggesting emerging correlations" between independent preand post-selected ensembles of particles. This can be viewed as a quantum violation of the classical pigeonhole principle".
