量子Cheshire猫实验中任意性质数的非具体化

Disembodiment of arbitrary number of properties in quantum Cheshire cat experiment

A. K. Pan

摘要:

量子柴郡猫是在弱测量的框架内证明的一种效应,该框架辅助后选择场景,其中量子粒子(猫)的属性(例如,grin)可以在空间上与其位置分离的位置中找到。在这项工作中,我们首先提出了有趣的变种量子柴郡猫的两个不同的属性的“猫”的dispository证明,使\emph{grin}和它的\emph{meowing}可以发现在两个不同的路径上的干涉仪,而猫是在另一个路径。我们进一步扩展这个建议的三qutrit和$d$ -qudit系统的一个单一的粒子。我们提供了草图的实验建议,通过使用路径,自旋和能量自由度的单个中子和路径,偏振和轨道角动量的单个光子来测试我们的计划。

英文摘要:

The quantum Cheshire cat is an effect demonstrated within the framework of weak measurement aided with post-selection scenario where the property (say, grin) of a quantum particle (the cat) can be found in a spatially separated location from its position. In this work, we first propose interesting variants of quantum Cheshire cat where disembodiment of two different properties of a `cat' is demonstrated, so that, the \emph{grin} and the \emph{meowing} of it can be found in two different paths on an interferometer while the cat is in another path. We further extend this proposal for three-qutrit and $d$-qudit systems of a single particle. We provide sketches of the experimental proposals for testing our scheme by using the path, spin and energy degrees of freedoms of a single neutron and the path, polarization and orbital angular momentum of a single photon.
