论文摘要
我们报告了一个低温离子陷阱系统的设计，制造和表征，用于实施由近场微波炉驱动的量子逻辑。该陷阱结合了带有电极几何形状的片上微波谐振器，旨在将其直接耦合到量子的微波磁场组件，同时为驱动纠缠逻辑门提供了较大的场梯度。我们使用单个$^{43} $ ca $^+$ ion绘制微波字段，并测量一个和两个离子的离子捕获寿命和运动模式加热率。
We report the design, fabrication, and characterization of a cryogenic ion trap system for the implementation of quantum logic driven by near-field microwaves. The trap incorporates an on-chip microwave resonator with an electrode geometry designed to null the microwave field component that couples directly to the qubit, while giving a large field gradient for driving entangling logic gates. We map the microwave field using a single $^{43}$Ca$^+$ ion, and measure the ion trapping lifetime and motional mode heating rates for one and two ions.
