论文摘要
我们描述了表面电极离子陷阱连接的设计，这是大尺度离子陷阱阵列的关键元素。双向目标优化方法用于设计电极，该方法保持了总伪电曲率，同时最小化沿离子传输路径的轴向伪电位梯度。为了促进在多个陷阱区域中平行操作的激光束输送，我们在此X偶口陷阱的每个臂上实现了集成的光学元件。提出了商业铸造制造的陷阱芯片的布局。这项工作建议在可扩展实现中改善离子陷阱连接性能的路线。连同集成的光学解决方案，这有助于互连的二维阵列中的模块化捕获 - 离子量子计算。
We describe the design of a surface-electrode ion trap junction, which is a key element for large-scale ion trap arrays. A bi-objective optimization method is used for designing the electrodes, which maintains the total pseudo-potential curvature while minimizing the axial pseudo-potential gradient along the ion transport path. To facilitate the laser beam delivery for parallel operations in multiple trap zones, we implemented integrated optics on each arm of this X-junction trap. The layout of the trap chip for commercial foundry fabrication is presented. This work suggests routes to improving ion trap junction performance in scalable implementations. Together with integrated optical addressing, this contributes to modular trapped-ion quantum computing in interconnected 2-dimensional arrays.
