The effective quantum field theory description of gravity, despite its non-renormalizability, allows for predictions beyond classical general relativity. As we enter the age gravitational wave astronomy, an important and timely question is whether measurable that depart from analogous to optics effects which cannot be explained by electrodynamics, can found. In this work, investigate signatures in waves using tools optics. Squeezed-coherent waves, exhibit sub-Poissonian graviton statistics, enhance or suppress signal measured interferometer, a characteristic effect squeezing. Moreover, show Gaussian states reconstructed measurements over ensemble optical fields interacting with single copy wave, thus opening possibility detecting features gravity
