Abstract: 
A different way to realize nonadiabatic geometric quantum computation is proposed by varying parameters
in the Hamiltonian for nuclear-magnetic resonance, where the dynamical and geometric phases are implemented
separately without the usual operational process. Therefore the phase accumulated in the geometric
gate is a pure geometric phase for any input state. In comparison with the conventional geometric gates by
rotating operations, our approach simplifies experimental implementations making them robust to certain
experimental errors. In contrast to the unconventional geometric gates, our approach distinguishes the total and
geometric phases and offers a wide choice of the relations between the dynamical and geometric phases.
