Finding a feasible protocol for probing the quantum nature of gravity hasbeen attracting an increasing amount of attention. In this manuscript, wepropose a protocol to enhance the detection of gravitationally inducedentanglement by exploiting the two-phonon drive in a hybrid quantum setup. Weconsider the setup consisting of a test particle in a double-well potential, aqubit and a quantum mediator. There is gravitational interaction between thetest particle and the mediator, and a spin-phonon coupling between the mediatorand the qubit. By introducing a two-phonon drive, the entanglement between theTP and the qubit are significantly enhanced and the entanglement generationrate is remarkably increased compared with the case without the two-phonondrive. Moreover, the entanglement between the TP and the qubit can be partiallypreserved in the presence of dephasing by the proposed strategy. This workwould open a different avenue for experimental detection of the quantum natureof gravity, which could find applications in quantum information science.
