Abstract
A strategy to perfectly preserve the two-qubit state is investigated in geometric quantum computation for nuclear magnetic resonance system. The results show that, by controlling the azimuthal angle in the initial state, we may realize the geometric quantum gate with a perfect fidelity under the geometric quantum computation. The way may be extended to other physical systems.
