Abstract: The present disclosure provides an ion trap apparatus and a saddle point moving method for the ion trap apparatus. The ion trap apparatus comprises: an insulating base material, the insulating base material being a concave structure; and at least two segments of arc-shaped metal reflective electrodes, wherein the arc-shaped metal reflective electrodes cover the front side of the insulating base material, the front side being a concave surface; each segment of the arc-shaped metal reflective electrodes is electrically insulated; and each segment of the arc-shaped metal reflective electrodes is used to receive a radio frequency voltage which has the same frequency, the same phase and an adjustable amplitude. The apparatus may achieve ideal imaging while improving the light collection efficiency, thereby improving the success rate of the preparation of ion-photon entangled states.
