研究了引力场真空涨落产生引力子与电磁场真空涨落产生光子之间的相似性。宇宙中产生的引力子和实验室中产生的光子都遵循类似的物理原理和数学方程。两者都是由所谓的压缩真空量子态描述的。在实验上，通过将抽运光从干涉仪中的压缩涨落中分离出来，产生了压缩真空光辐射。引力理论的某些预言可以在实验室里通过量子光学实验来模拟，甚至检验
The close analogy between the generation of gravitons from vacuum fluctuations of the gravitational field and the generation of photons from vacuum fluctuations of the electromagnetic field is studied. Gravitons produced in the cosmos and photons produced in the laboratory are governed by similar physical principles and mathematical equations. Both are described by the so-called squeezed vacuum quantum states. Squeezed vacuum optical radiation has been generated experimentally by separating the pump light from the squeezed fluctuations in an interferometric geometry. It may prove possible that some predictions of gravitation theory can be modeled, or even tested, in the laboratory by quantum optics experiments
