消失（和重新出现）的粒子
The Case of the Disappearing (and Re-Appearing) Particle
摘要：
利用双态矢量形式（TSVF）对一个叠加在三个盒子上的粒子进行了新的预测。在适当的预选择和后选择下，并且在两个框之间启用隧道，可以在中间间隔内针对三个不同时间导出不仅一个，而是三个预测。而且，这些预测相互矛盾。粒子（当使用投影测量时）似乎从第一个盒子里消失了，在那里它以前肯定会被发现，而是出现在第三个盒子里，不可能有隧道，后来又出现在第二个盒子里。事实证明，局部测量（即打开其中一个盒子）未能表明粒子的存在，但对两个盒子一起进行的更微妙的测量揭示了粒子的非局部模动量在空间上与其质量分离。这种设置的另一个优点是，与其他依赖于弱和/或反事实测量的TSVF预测不同，本预测使用实际投影测量。然后通过添加弱测量和Aharonov-Bohm效应来证实这一结果。结果加强了最近提出的时间对称海森堡本体论的基础上非本地确定性运营商。它们也可以使用新开发的量子路由器进行测试。
英文摘要：
A novel prediction is derived by the Two-State-Vector-Formalism (TSVF) for a particle superposed over three boxes. Under appropriate pre- and postselections, and with tunneling enabled between two of the boxes, it is possible to derive not only one, but three predictions for three different times within the intermediate interval. These predictions are moreover contradictory. The particle (when looked for using a projective measurement) seems to disappear from the first box where it would have been previously found with certainty, appearing instead within the third box, to which no tunneling is possible, and later re-appearing within the second. It turns out that local measurement (i.e. opening one of the boxes) fails to indicate the particle's presence, but subtler measurements performed on the two boxes together reveal the particle's nonlocal modular momentum spatially separated from its mass. Another advance of this setting is that, unlike other predictions of the TSVF that rely on weak and/or counterfactual measurements, the present one uses actual projective measurements. This outcome is then corroborated by adding weak measurements and the Aharonov-Bohm effect. The results strengthen the recently suggested time-symmetric Heisenberg ontology based on nonlocal deterministic operators. They can be also tested using the newly developed quantum router.
