论文摘要
我们研究了重力子诱导的量子噪声和破坏性。我们在存在引力物的情况下得出了地球偏差的兰格文方程。噪声相关性的幅度告诉我们，要检测噪声是必要的大挤压。我们还考虑了由吸引力在真空状态下引起的两个巨大颗粒的空间叠加的破坏性，并发现重力可以对腐蚀产生相关的贡献。重力造成的变形性将提供新的远景来测试桌面实验中的量子重力。
We study quantum noise and decoherence induced by gravitons. We derive a Langevin equation of geodesic deviation in the presence of gravitons. The amplitude of noise correlations tells us that large squeezing is necessary to detect the noise. We also consider the decoherence of spatial superpositions of two massive particles caused by gravitons in the vacuum state and find that gravitons could give a relevant contribution to the decoherence. The decoherence induced by gravitons would offer new vistas to test quantum gravity in tabletop experiments.
