  • Gradiometer-based flux qubit for quantum computing and method therefor
    Patent number: 6984846
    Abstract: A qubit (quantum bit) circuit includes a superconducting main loop that is electrically-completed by a serially-interconnected superconducting subloop. The subloop includes two Josephson junctions. A first coil provides a first flux that couples with the main loop but not with the subloop. A second coil provides a second flux that couples with the subloop but not with the main loop.
    Type: Grant
    Filed: August 27, 2003
    Date of Patent: January 10, 2006
    Assignee: International Business Machines Corporation
    Inventors: Dennis M. Newns, David P. DiVincenzo, Roger H. Koch, Glenn J. Martyna, Jim Rozen, Chang Chyi Tsuei
