标题： Comments on graviton detection

摘要： 有可能制造出一种探测器，在吸收单个引力子后会发出咔哒声。 同样地，也有可能制造出一种引力波探测器，能够观测到由某些高度压缩的引力子态引起的量子噪声。 然而，与文献中一些最近的论点相反，观测到其中任何一个信号，甚至同时观测到这两个信号，并不能构成证明，甚至不能作为引力场被量子化的证据。 这是一个简单的技术陈述：经典引力波可以在探测器中产生相同的数据输出。 在这里，我们解释了这一结果，该结果先前发表于arXiv:2308.12988，它是量子光学中一个古老论点的直接扩展。 显示英文摘要

摘要： It is possible to make a detector which clicks after absorbing a single graviton. Similarly, it is possible to make a gravitational wave detector which can see the quantum noise induced by certain highly squeezed states of the graviton. However, contrary to some recent arguments in the literature, observation of either or both of these signals would not constitute proof or even evidence that the gravitational field is quantized. This is a simple technical statement: a classical gravitational wave can produce the same output data in a detector. Here we explain this result, presented earlier in arXiv:2308.12988, which is a straightforward extension of an ancient argument in quantum optics.
