摘要We investigate an effective grooved 2D ion chip design and optimize the ratio between the size of the rf electrodes and the groove. We calculate the optimal size of the groove using the analytical model, which was introduced by House, and the optimum result is obtained. We also obtain the simulated scattering points with the finite element analysis method. The analytical curve and simulated scattering points are coincident with each other. It is shown that this analytical model also fits for the grooved planar ion chip. Thus the optimum grooved 2D planar ion chip design could be obtained. It is effective for scalable quantum information processing.
