表面电极离子阱结的优化与实现

Optimization and implementation of a surface-electrode ion trap junction

Chi Zhang, Karan K Mehta, Jonathan P Home

摘要:

我们描述了一个表面电极离子阱结的设计,这是一个大规模的离子阱阵列的关键元件。采用双目标优化方法设计电极,在保持总赝势曲率的同时,使离子传输路径上的轴向赝电势梯度最小化。为了便于激光束在多个阱区中的并行操作,我们在X结阱的每个臂上安装了集成光学器件。提出了用于商业代工制造的陷阱芯片的布局。这项工作提出了路线,以提高离子阱结的性能,在可扩展的实现。与集成光学寻址一起,这有助于在互连的2维阵列中进行模块化捕获离子量子计算。

英文摘要:

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.
