• Abstract: We introduce an innovative method to explore gravity's quantum aspects using a novel theoretical framework. Our model delves into gravity-induced entanglement (GIE) while sidestepping classical communication limitations imposed by the LOCC principle. Specifically, we connect a non-relativistic two-dimensional quantum oscillator detector with linearly polarized gravitational waves (GWs), leveraging the quantum properties inherent in GWs to observe GIE within the oscillator's quantum states. Because our model adheres to both the ``event" and the ``system" localities, the detected GIE serves as a robust indicator of gravity's quantum nature. Detecting this entanglement via gravitational wave detectors could corroborate gravity's quantization and unveil crucial properties of its sources.

  This paper explores the quantum and classical descriptions of gravitational wave detection in interferometers like LIGO. We demonstrate that while a simple graviton scattering model fails to explain the observed arm displacements, both the classical gravitational wave approach and a quantum gravitational energy method successfully predict the correct results.

  We show the existence of genuine tripartite non-Gaussian entanglement in a quantum gravitational system. We introduce a new entanglement witness, well-suited for the graviton-matter interaction Hamiltonian analysed here. We show that the witness is non-zero for the three-mode states generated by the Hamiltonian when the system starts in the ground state.

  Using LIGO's arms as oscillators interacting with gravitational waves (GWs), our study demonstrates the potential for generating quantum entanglement. Our findings reveal unique entanglement dynamics, including periodic "collapse and revival" influenced by GW oscillations, alongside a distinct "quantum memory effect" We believe that these forecasts may hold significance towards both theoretically probing and experimentally verifying various properties of classical gravitational waves.
