Abstract
Section titled āAbstractāWe propose a feasible scheme to implement a universal set of quantum gates\nbased on geometric phases and superadiabatic quantum control. Consolidating the\nadvantages of both strategies, the proposed quantum gates are robust and fast.\nThe diamond nitrogen-vacancy center system is adopted as a typical example to\nillustrate the scheme. We show that these gates can be realized in a simple\ntwo-level configuration by appropriately controlling the amplitude, phase, and\nfrequency of just one microwave field. The gateās robust and fast features are\nconfirmed by comparing the fidelity of the proposed superadiabatic geometric\nphase (controlled-PHASE) gate with those of two other kinds of phase\n(controlled-PHASE) gates.\n
