    "abstract": "In a scheme of nonadiabatic purely geometric quantum gates in nuclear\nmagnetic resonance(NMR) systems we propose proper magnitudes of magnetic fields\nthat are suitable for an experiment. We impose a natural condition and reduce\nthe degree of freedom of the magnetic fields to the extent. By varying the\nmagnetic fields with essentially one-dimensional degree of freedom, any spin\nstate can acquire arbitrary purely geometric phase\n\\phi_{g}=-2\\pi(1-cos{theta}), 0 \u003c cos{\\theta} \u003c 1. This is an essential\ningredient for constructing universal geometric quantum gates.",
