标题： Quantization of Gravitational Waves and Squeezing

摘要： 是否引力波是量子化的，原则上可以通过相关测量来回答。 如果引力波是量子化的，并且它们是由背景度规的变化产生的，那么它们可以处于压缩态。 在压缩态中，波的相位与量子涨落之间存在相关性。 建议从这种相关性的角度分析引力探测器将获得的数据。 推导出了量子化引力波的压缩参数的显式公式。 分析了两个相同黑洞的正面碰撞作为可能产生压缩引力波的来源。 显示英文摘要

摘要： The question whether gravitational waves are quantised or not can in principle be answered by the help of correlation measurements. If the gravitational waves are quantised and they are generated by the change of the background metrics then they can be in squeezed state. In a sqeezed state there is a correlation between the phase of the wave and the quantum fluctuations. It is recommended to analyse the data to be obtained by the gravitational detectors from the point of view of such correlations. An explicit formula is derived for the squeezing parameter of the quantised gravitational waves. The head on collision of two identical black holes is analysed as a possible source of squeezed gravitational waves.
