论文摘要
我们介绍了原型表面电极（SE）陷阱的表征，这是实现基于Yb $^+$的紧凑型单离子光学时钟的第一步。使用SE陷阱将是从量子信息处理领域所取得的清洁室制造技术和技术进步中受益的关键因素。我们成功地证明了在500 $ $ m电极距离的捕获，并在寿命和加热速率方面表征了我们的陷阱。据我们所知，这是SE陷阱中的加热速率测量所取得的最高距离。这种简单的5线设计用简单的材料实现，产生的加热速率为$ \ mathbf {8 \ times 10^3} $ phonons/s。我们提供了用于光学频率计量学的该原型陷阱的性能的分析。
We present the characterization of a prototype surface-electrode (SE) trap as a first step towards the realization of a compact, single-ion optical clock based on Yb$^+$. The use of a SE trap will be a key factor to benefit from clean-room fabrication techniques and technological advances made in the field of quantum information processing. We succesfully demonstrated trapping at a 500 $μ$m electrodes distance and characterized our trap in terms of lifetime and heating rate. This is to our knowledge the highest distance achieved for heating rates measurements in SE traps. This simple 5-wire design realized with simple materials yields a heating rate of $\mathbf{8\times 10^3}$ phonons/s. We provide an analysis of the performances of this prototype trap for optical frequency metrology.
