    "abstract": "We study a device consisting of a dc-SQUID with two sections of its loop\nacting as two mechanical resonators. An analog of the parametric\ndown-conversion process in quantum optics can be realized with this device. We\nshow that a two-mode squeezed state can be generated for two overdamped\nmechanical resonators, where the damping constants of the two mechanical\nresonators are larger than the coupling strengths between the dc-SQUID and the\ntwo mechanical resonators. Thus we show that entangled states of these two\nmechanical resonators can be generated.",
