Josephson Vortex Qubit: Design, Preparation adn Read-Out

233_03/2002Algorithms based on quantum logic represent an exciting prospect for the development of advanced and even more powerful computers. The cover picture of the present issue shows an optical microscopy image of a heart-shaped Josephson junction with a radius of 50 μm. These junctions are designed to generate a double-well potential for a vortex qubit moving in the junction, which may be used for quantum computation.The paper is a presentation from the 275th WE-Heraeus-Seminaron Hardware Concepts for Quantum Computing, May 13–15, 2002, Bad Honnef (Germany). The purpose of this workshop was to provide a forum for the presentation of the different concepts for the realisation of quantum computing with solid-state devices. Of particular interest were devices based on semiconductors, superconductors, magnetic thin films or molecular systems. Theoretical approaches, state-of-the-art results of experimental realisation as well as technological issues were discussed. The proceedings in this issue are guest-edited by M. S. Brandt, M. Fanciulli and M. Stutzmann
