Entanglement between charge qubit states and coherent states of nanomechanical resonator generated by AC Josephson effect

O. M. Bahrova, L Y. Gorelik, S. I. Kulinich

We considered a nanoelectromechanical system consisting of a movable Cooper-pair box qubit which is subject to an electrostatic field, and coupled to the two bulk superconductors v…
