论文摘要
我们描述了表面电极Paul陷阱的设计和操作，用于并行纠缠门实现。特别是，我们通过调整一组电极上的DC-电压来证明分离或耦合离子运动的可能性，并显示特定电压配置的并行MS-GATE操作的可能性。我们验证这种方法的可伸缩性，并在有限的声子模式占用和声子频率的有限漂移的情况下表征这些门的性能。此外，我们研究了每个单个捕获位点的离子数量和非谐势术语如何影响井之间的耦合。
We describe the design and operation of a surface-electrode Paul trap for parallel entangling gate implementation. In particular, we demonstrate the possibility of separating or coupling ion motion by adjusting the DC-voltages on a set of electrodes and show the possibility of parallel MS-gate operations for specific voltage configurations. We verify the scalability of this approach and characterize the performance of these gates in the presence of the finite phonon mode occupation and of the finite drift of the phonon frequencies. Additionally, we investigate how the number of ions per individual trapping site and anharmonic potential terms affect the coupling between the wells.
