Theories of quantum gravity based on the holographic principle predict theexistence of quantum fluctuations of distance measurements that accumulate andexhibit correlations over macroscopic distances. This paper models an expectedsignal due to this phenomenology, and details the design and estimatedsensitivity of co-located twin table-top 3D interferometers being built tomeasure or constrain it. The experiment is estimated to be sensitive todisplacements $\sim10^{-19}\,\rm{m}/\sqrt{\rm{Hz}}$ in a frequency band between1 and 250 MHz, surpassing previous experiments and enabling the possibleobservation of quantum gravity phenomena. The experiment will also be sensitiveto MHz gravitational waves and various dark matter candidates.
