Recent proposals are emerging for the experimental detection of entanglement
mediated by classical gravity, carrying significant theoretical and
observational implications. In fact, the detection of gravitational waves (GWs)
in LIGO provides an alternative laboratory for testing various gravity-related
properties. By employing LIGO’s arms as oscillators interacting with
gravitational waves (GWs), our study demonstrates the potential for generating
quantum entanglement between two mutually orthogonal modes of simple harmonic
oscillators. 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 for both theoretically probing and experimentally verifying the
quantumness of gravitational waves.
