    "abstract": "We study theoretically a radio frequency superconducting interference device\nintegrated with both a nanomechanical resonator and an LC one. By applying\nadiabatic and rotating wave approximations, we obtain an effective Hamiltonian\nthat governs the dynamics of the mechanical and LC resonators. Nonlinear terms\nin this Hamiltonian can be exploited for performing a quantum nondemolition\nmeasurement of Fock states of the nanomechanical resonator. We address the\nfeasibility of experimental implementation and show that the nonlinear coupling\ncan be made sufficiently strong to allow the detection of discrete mechanical\nFock states.",
