- Abstract: A proposal for an improved theoretical model to illuminate the quantum nature of gravity is given. This model investigates the gravity-induced entanglement (GIE) phenomena, circumventing classical communication constraints of LOCC principle. Here a non-relativistic two dimensional quantum oscillator detector is coupled to linearly polarized gravitational waves (GWs). Exploiting the quantum nature of GWs, we observe the GIE within the oscillator quantum states. Since the model satisfies ``event'' as well as ``system'' localities, the observed GIE is much robust signature for quantum nature of gravity.
