Operation of universal gates in a solid-state quantum computer based on clean Josephson junctions between d -wave superconductors

Operation of universal gates in a solid-state quantum computer based on clean Josephson junctions... The operation of a solid-state superconducting quantum computer based on clean Josephson junctions between two d -wave superconductors is considered. We show that freezing of passive qubits can be achieved using a dynamic global refocusing technique. Further, we demonstrate that a universal set of gates can be realized on this system, thereby proving its universality. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review A American Physical Society (APS)

Abstract

The operation of a solid-state superconducting quantum computer based on clean Josephson junctions between two d -wave superconductors is considered. We show that freezing of passive qubits can be achieved using a dynamic global refocusing technique. Further, we demonstrate that a universal set of gates can be realized on this system, thereby proving its universality.
