论文摘要
量子相关的存在会影响显微镜和宏观系统。在宏观系统上，由于与环境的频繁交换，它们很难观察，并且通常与系统的演变无关。全球引力波（GW）天文台的网络利用光学以及高度宏观的机械系统，并且在很大程度上与环境解耦。公里尺度臂共振器中的准单色光场具有大于$ 10^{19} $的光子激发数，而无准的镜子沿着光场的传播方向落入质量约为40 kg。对GW观测值Ligo和处女座的最新观察清楚地表明，一个系统的量子不确定性影响了另一个系统的不确定性。在这里，我们回顾了这些观察结果，并提供了针对其他基本物理研究领域中介镜光学系统目标的研究目标的链接。这些可能具有高斯量子不确定性，就像GW观测值甚至非高斯量子一样，例如Schrödinger猫的状态。
The existence of quantum correlations affects both microscopic and macroscopic systems. On macroscopic systems they are difficult to observe and usually irrelevant for the system's evolution due to the frequent energy exchange with the environment. The world-wide network of gravitational-wave (GW) observatories exploits optical as well as mechanical systems that are highly macroscopic and largely decoupled from the environment. The quasi-monochromatic light fields in the kilometre-scale arm resonators have photon excitation numbers larger than $10^{19}$, and the mirrors that are quasi-free falling in propagation direction of the light fields have masses of around 40 kg. Recent observations on the GW observatories LIGO and Virgo clearly showed that the quantum uncertainty of one system affected the uncertainty of the other. Here, we review these observations and provide links to research goals targeted with mesoscopic optomechanical systems in other fields of fundamental physical research. These may have Gaussian quantum uncertainties as the ones in GW observatories or even non-Gaussian ones, such as Schrödinger cat states.
