量子柴郡猫的咧嘴和咆哮路径选择的延迟选择
Delayed choice of paths selected by grin and snarl of quantum Cheshire Cat
摘要:
所谓的量子柴郡猫是一种场景,其中一个光子(被认为是猫)和它的偏振分量(被认为是猫的笑容)被分离。我们观察到,同样的技术可以用来分离两个正交分量的偏振的光子,平均。为了便于理解,我们将光子的这些偏振分量标识为猫的咧嘴笑和咆哮。本文介绍了一个同时调谐马赫-曾德尔干涉仪两臂入射光子偏振态的实验。注意,对于光子偏振的两个特定选择,两个分量的存在在两个臂中被反转。在偏振分量甚至与调谐器相互作用之前,即,在选择每个人应该在哪个手臂之前。
英文摘要:
The so-called quantum Cheshire Cat is a scenario where a photon, identified with a cat, and a component of its polarization, identified with the grin of that cat, are separated. We observe that the same techniques can be used to separate two orthogonal components of polarization of a photon, on an average. We identify these polarization components of the photon as the grin and snarl of the cat for ease of comprehension. A gedanken experiment is presented in which we simultaneously tune the input polarizations of the photon in the two arms of a Mach-Zehnder interferometer. It is noted that for two particular choices of photon polarization, the presence of the two components gets reversed in the two arms. This reversal of the grin and the snarl occurs before the polarization components even interact with the tuners, i.e., before the choice of which arm each should be in is made.
