基于全息原理的量子引力理论预测了距离测量的量子涨落的存在，这些涨落在宏观距离上积累并表现出相关性。本文模拟了这种现象所产生的预期信号，并详细介绍了用于测量或约束该信号的双桌面3D干涉仪的设计和估计灵敏度。该实验估计对1至250 MHz频带内的位移灵敏度为10− 19 m/Hz，超过了以前的实验，使量子引力现象的观测成为可能。该实验还将对MHz引力波和各种暗物质候选者敏感。
Theories of quantum gravity based on the holographic principle predict the existence of quantum fluctuations of distance measurements that accumulate and exhibit correlations over macroscopic distances. This paper models an expected signal due to this phenomenology, and details the design and estimated sensitivity of co-located twin table-top 3D interferometers being built to measure or constrain it. The experiment is estimated to be sensitive to displacements ∼10−19m/Hz in a frequency band between 1 and 250 MHz, surpassing previous experiments and enabling the possible observation of quantum gravity phenomena. The experiment will also be sensitive to MHz gravitational waves and various dark matter candidates.
