Quantum bits by electrostatic gating superconducting rings KU Leuven
The disclosed technology generally relates to superconducting devices, and more particularly to superconducting rings, qubits comprising the superconducting rings and methods of coherently coupling flux states of the superconducting rings. In one aspect, a qubit includes a superconducting ring around a hole. The qubit additionally includes an electric field generator adapted for applying an electric field in a plane of the superconducting ring over at least part of the superconducting ring, and a magnetic field generator adapted for applying a magnetic field component orthogonal to the plane ...
