We report on a demonstration of Ramsey interferometry by three-dimensional motion with a trapped ^{171}Yb^{+} ion. We applied a momentum kick to the ion in a direction diagonal to the trap axes to initiate three-dimensional motion using a mode-locked pulse laser. The interference signal was analyzed theoretically to demonstrate three-dimensional matter-wave interference. This work paves the way to realizing matter-wave interferometry using trapped ions.
我们报道了利用囚禁的(^{171}Yb^{+})离子通过三维运动进行拉姆齐干涉测量的演示。我们使用锁模脉冲激光，在与阱轴成对角线的方向上对离子施加动量踢，以启动三维运动。对干涉信号进行了理论分析，以证明三维物质波干涉。这项工作为利用囚禁离子实现物质波干涉测量铺平了道路。
