    "abstract": "Many protocols for quantum computation require a quantum memory element to\nstore qubits. We discuss the accuracy with which quantum states prepared in a\nJosephson junction qubit can be stored in a nanoelectromechanical resonator and\nthen transfered back to the junction. We find that the fidelity of the memory\noperation depends on both the junction-resonator coupling strength and the\nlocation of the state on the Bloch sphere. Although we specifically focus on a\nlarge-area, current-biased Josesphson junction phase qubit coupled to the\ndilatational mode of a piezoelectric nanoelectromechanical disk resonator, many\nour results will apply to other qubit-oscillator models.",
