A recent neutron interferometry experiment claims to demonstrate a paradoxical phenomenon dubbed the "quantum Cheshire cat" [Nat. Commun.5, 4492 (2014)]. We have reproduced and extended these results with an equivalent optical interferometer. The results suggest that the photon travels through one arm of the interferometer, while its polarization travels through the other. However, we show that these experimental results belong to the domain where quantum and classical wave theories coincide; there is nothing uniquely quantum about the illusion of this Cheshire cat.
最近的一项中子干涉测量实验声称证明了一种被称为“量子柴郡猫”的矛盾现象[《自然·通讯》5, 4492 (2014)]。我们用一个等效的光学干涉仪重现并扩展了这些结果。结果表明，光子通过干涉仪的一条臂传播，而其偏振则通过另一条臂传播。然而，我们表明这些实验结果属于量子和经典波动理论一致的领域；这种柴郡猫的幻象并没有什么独特的量子特性。
