论文摘要
我们报告了带有集成波导的微生物表面离子陷阱上加热速率和光诱导的电荷的表征。由于其可伸缩性和制造性,微生物表面离子陷阱作为量子信息平台受到了相当大的关注。在这里,我们表征了435 nm的光线通过波导和衍射耦合器在紧凑型陷阱中的单个ytterbium离子传递。我们在室温下测量轴向加热速率为$ 0.78 \ pm0.05 $ q/ms,由于存在波导而没有增加增加。此外,由于裸露的介电外耦合器的充电而导致的电场在初次移动后正常运行下沉降。沉降后的频率不稳定性为0.9 kHz。
We report on the characterization of heating rates and photo-induced electric charging on a microfabricated surface ion trap with integrated waveguides. Microfabricated surface ion traps have received considerable attention as a quantum information platform due to their scalability and manufacturability. Here we characterize the delivery of 435 nm light through waveguides and diffractive couplers to a single ytterbium ion in a compact trap. We measure an axial heating rate at room temperature of $0.78\pm0.05$ q/ms and see no increase due to the presence of the waveguide. Furthermore, the electric field due to charging of the exposed dielectric outcoupler settles under normal operation after an initial shift. The frequency instability after settling is measured to be 0.9 kHz.
