论文摘要
量子柴郡猫是在弱测量框架内证明的效果，该效果在选择后场景中有助于量子粒子（例如，grin）的量子粒子（猫）（猫）的效果，可以在空间分离的位置与其位置找到。在这项工作中，我们首先提出了量子cheshire猫的有趣变体，其中证明了“猫”的两种不同特性的分析，因此，可以在猫在另一个路径上的干扰仪上以两种不同的路径找到\ emph {grin}和\ emph {meowing}。我们进一步扩展了单个粒子的三qutrit和$ d $ qudit系统的建议。我们通过使用单个光子的单个中子和路径，偏振和轨道角动量的路径，自旋和能量度来测试我们的方案的实验建议草图。
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.
