摘要

摘要:我们报道了一种低温离子阱系统的设计、制造和表征，该系统用于近场微波驱动量子逻辑的实现。该陷阱集成了一个芯片上的微波谐振器，其电极几何结构设计用于消除直接耦合到量子位的微波场组件，同时提供大的场梯度来驱动纠缠逻辑门。我们使用单个43Ca+离子绘制微波场图，并测量了一个和两个离子的离子捕获寿命和运动模式加热速率。

Cryogenic ion trap system for high-fidelity near-field microwave-driven quantum logic

Abstract 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 43Ca+ ion, and measure the ion trapping lifetimeand motional mode heating rates for one and two ions.

期刊介绍： Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
