We report on the design and testing of an array of Penning ion traps made from printed circuit board. The system enables fast shuttling of ions from one trapping zone to another, which could be of use in quantum information processing. We describe simulations carried out to determine the optimal potentials to be applied to the trap electrodes for enabling this movement. The results of a preliminary experiment with a cloud of laser cooled calcium ions demonstrate a round-trip shuttling efficiency of up to 75%.
我们报告了一种由印刷电路板制成的潘宁离子阱阵列的设计与测试。该系统能够使离子快速从一个捕获区域穿梭至另一个区域，这在量子信息处理中可能会有用处。我们描述了为确定施加于阱电极以实现这种移动的最佳电势而进行的模拟。对一团激光冷却钙离子进行的初步实验结果表明，往返穿梭效率高达75%。
