    "abstract": "We propose a technique to couple the position operator of a nano mechanical\nresonator to a SQUID device by modulating its magnetic flux bias. By tuning the\nmagnetic field properly, either linear or quadratic couplings can be realized,\nwith a discretely adjustable coupling strength. This provides a way to realize\ncoherent nonlinear effects in a nano mechanical resonator by coupling it to a\nJosephson quantum circuit. As an example, we show how squeezing of the nano\nmechanical resonator state can be realized with this technique. We also propose\na simple method to measure the uncertainty in the position of the nano\nmechanical resonator without quantum state tomography.",
