TL;DR: The Fermilab Holometer as discussed by the authors, a 39-meter Michelson interferometer, was used to place limits on the mass range of primordial black hole binaries.

TL;DR: The Fermilab Holometer obtains sensitivity to high frequency correlated signals far exceeding any previous measurement in a broad frequency band extending beyond the 3.8 MHz inverse light-crossing time of the apparatus.

TL;DR: The Fermilab Holometer as mentioned in this paper is an instrument for measuring correlations of position variations over a four-dimensional volume of space-time, and is used to verify shot-noise-limited performance.

TL;DR: The first-generation Holometer as mentioned in this paper is the first instrument capable of measuring correlated variations in space-time position at strain noise power spectral densities smaller than a Planck time.

TL;DR: In this article, the effect of Planck scale quantum geometrical effects on measurements with interferometers is estimated with standard physics, and with a variety of proposed extensions, and it is shown that effects are negligible in standard field theory with canonically quantized gravity.
