We have developed a trapped ion system for producing two-dimensional (2D) ion crystals for applications in scalable quantum computing, quantum simulations, and 2D crystal phase transition and defect studies. The trap is a modification of a Paul trap with its ring electrode flattened and split into eight identical sectors and its two endcap electrodes shaped as truncated hollow cones for laser and imaging optics access. All ten trap electrodes can be independently DC-biased to create various aspect ratio trap geometries. We trap and Doppler cool 2D crystals of up to 30 Ba ions and demonstrate the tunability of the trapping potential both in the plane of the crystal and in the transverse direction.
我们开发了一种捕获离子系统，用于生产二维（2D）离子晶体，以应用于可扩展量子计算、量子模拟以及二维晶体相变和缺陷研究。该陷阱是对保罗阱的一种改进，其环形电极被压扁并分成八个相同的扇区，两个端盖电极被制成截顶空心圆锥形状，以便激光和成像光学器件能够接入。所有十个陷阱电极都可以独立地进行直流偏置，以创建各种纵横比的陷阱几何形状。我们捕获并多普勒冷却多达30个钡离子的二维晶体，并展示了捕获势在晶体平面内和横向方向上的可调性。
