论文摘要
我们已经开发了一种用于在可扩展量子计算，量子模拟和2D晶体相变和缺陷研究中应用的二维（2D）离子晶体的捕获离子系统。该陷阱是对保罗陷阱的修饰，其环电极扁平并分成八个相同的扇区，其两个端盖电极形状为截短的空心锥，用于激光和成像光学元件。所有十个陷阱电极都可以独立地偏向偏置，以创建各种纵横比陷阱几何形状。我们陷阱和多普勒冷却的2D晶体最多30 ba+离子，并在晶体平面和横向方向上演示了捕获势的可调性。
We have developed an 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.
