论文摘要
在最近的一项工作[Arxiv：2004.07451]中，Kim等人声称是对量子柴郡CAT效应的第一个真正的实验观察。我们以这一主张为由，理由是，所采用的设置不足以进行定义这种干涉效应的弱测量。未观察到一半必需的弱值，另一半是通过将结果与不同的设置结合的结果间接获得的。
In a very recent work [arXiv:2004.07451], Kim et al claimed to have made the first genuine experimental observation of the Quantum Cheshire Cat effect. We dispute this claim on the ground that the setup employed is not adequate for making the weak measurements that define this interferometric effect. Half of the necessary weak values are not observed, and the other half is obtained indirectly by combining results measured with distinct setups.
