# Gravito-optics and intensity correlations for binary inspiral signal detections

## TL;DR

This paper develops a new gravito-optics framework for analyzing intensity correlations in transient gravitational wave signals from binary inspirals, extending previous theories focused on cosmological sources and periodic signals.

## Contribution

It introduces a novel gravito-optics approach for transient signals from binary coalescences and discusses the quantum aspects of intensity correlations in gravitational wave detection.

## Key findings

- Calculated two-point intensity correlations for gravitational wave signals.
- Extended gravito-optics theory to transient, non-periodic signals.
- Outlined necessary theoretical developments for quantum gravito-optics in this context.

## Abstract

We examine the correlation functions associated with intensity interferometry and gravito-optics of gravitational wave signals from compact binary coalescences. Previous theoretical studies of the gravito-optics of gravitational waves has concentrated on the characterization of both the classical and the non-classical properties of signals from cosmological sources in the early Universe. These previous works assume a periodic signal similar to the signals studied widely in optics and quantum optics and do not apply to transient signals. We develop the gravito-optics of intensity correlations for descriptions of the detection of transient signals from compact binary coalescences and apply these methods to calculate the two-point intensity correlations for the gravitational wave discovery. We also discuss the necessary theoretical work required for the description of the quantum gravito-optics of intensity correlations in the detection of signals from binary inspirals.
