我们在分段微结构保罗陷阱中实现了离子的快速传输。在陷阱的仅五个运动周期内（3.6μs内280μm），离子穿梭的距离超过其基态波函数大小的10（4）倍。从基态冷却离子开始，我们找到了一种优化的传输方式，使得能量增加低至 0.10 +/- 0.01 动量子。此外，我们证明了以自旋运动纠缠态存储的量子信息在整个传输过程中得以保留。穿梭操作被串联起来，作为基于穿梭的架构到可扩展离子阱量子计算的原理验证。
We realize fast transport of ions in a segmented microstructured Paul trap. The ion is shuttled over a distance of more than 10(4) times its ground state wave function size during only five motional cycles of the trap (280 mu m in 3.6 mu s). Starting from a ground-state-cooled ion, we find an optimized transport such that the energy increase is as low as 0.10 +/- 0.01 motional quanta. In addition, we demonstrate that quantum information stored in a spin-motion entangled state is preserved throughout the transport. Shuttling operations are concatenated, as a proof-of-principle for the shuttling-based architecture to scalable ion trap quantum computing.
