Abstract
Section titled āAbstractāWe propose fast phase-gates of single nuclear spins interacting with single\nelectron spins. The gate operation utilizes geometric phase shifts of the\nelectron spin induced by fast/slow rotating fields; the path difference\ndepending on nuclear spin states enables nuclear phase shifts. The gate time is\ninversely proportional to the frequency of the slow rotating field. As an\nexample, we use nitrogen-vacancy centers in diamond, and show the phase-gate\ntime orders of magnitude shorter than previously reported. We also show the\nrobustness of the gate against decoherence and systematic errors.\n
