Nanomechanical cat states generated by a dc voltage-driven Cooper pair box qubit
Abstract We study a nanoelectromechanical system consisting of a Cooper pair box qubit performing nanomechanical vibrations between two bulk superconductors. We demonstrate that a bias voltage applied to the superconductors may generate states represented by entanglement between qubit states and qua...
