论文摘要
我们描述了超低振动闭合循环低温离子陷阱设备的设计，调试和操作。低频信号和八个微波 /射频同轴饲料线的一百行提供了实现小型离子陷阱量子处理器或模拟器的可能性。随着所有电源电缆的连接，仍可以使用5 K时的冷却功率超过1.3 W，可用于吸收引入控制离子的电脉冲的能量。陷阱本身是从使用氦气交换气体界面引起的振动中分离出来的。振动隔离系统的性能已经使用米歇尔森干涉仪进行表征，发现了10 nm RMS的剩余振动幅度。 $^9 $ be $^+$ ions的捕获已通过激光消融和光电离来证明。
We describe the design, commissioning and operation of an ultra-low-vibration closed-cycle cryogenic ion trap apparatus. One hundred lines for low-frequency signals and eight microwave / radio frequency coaxial feed lines offer the possibility of implementing a small-scale ion-trap quantum processor or simulator. With all supply cables attached, more than 1.3 W of cooling power at 5 K is still available for absorbing energy from electrical pulses introduced to control ions. The trap itself is isolated from vibrations induced by the cold head using a helium exchange gas interface. The performance of the vibration isolation system has been characterized using a Michelson interferometer, finding residual vibration amplitudes on the order of 10 nm rms. Trapping of $^9$Be$^+$ ions has been demonstrated using a combination of laser ablation and photoionization.
