Voltage control in a three-junction flux qubit — •Luca Chirolli and Guido Burkard — Department of Physics-University of Basel-Basel-Switzerland

By means of a general circuit analysis, we study a superconducting flux qubit with three Josephson junction in which enhanced control is achieved by introducing electrostatic gates. We discuss the additional terms in the single-qubit Hamiltonian due to an applied gate voltage.
