摘要
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.
