评“用非侵入性弱测量观测“量子柴郡猫”效应“

Comment on "Observing the "quantum Cheshire cat" effect with noninvasive weak measurement''

Surya Narayan Sahoo, Dipankar Home, Alex Matzkin, Urbasi Sinha

摘要:

在最近的一项工作中[arXiv:2004.07451],Kim等人声称已经对量子柴郡猫效应进行了第一次真正的实验观察。我们对这种说法提出异议,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。一半的必要的弱值没有观察到,另一半是通过组合不同设置测量的结果间接获得的。

英文摘要:

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.
