摘要

离子阱的应用范围很广，从计量学到量子模拟和量子信息处理。基于微晶片的3D离子阱具有可扩展性，可存储大量离子以实现大量量子位，与表面阱相比，具有较深的捕获电位，并且对外部电场有很好的屏蔽作用。在这项工作中，我们概述了我们基于芯片的3D离子阱的最新发展。讨论了不同类型的芯片材料、片上电子滤波元件的集成以及真空中紧凑的电气连接。此外，基于有限元模拟，我们讨论了如何在不干扰被捕获离子的情况下将微光学集成到三维离子阱中。

Scalable chip-based 3D ion traps

Ion traps are used for a wide range of applications from metrology to quantum simulations and quantum information processing. Microfabricated chip-based 3D ion traps are scalable to store many ions for the realization of a large number of qubits, provide deep trapping potentials compared to surface traps, and very good shielding from external electric fields. In this work, we give an overview of our recent developments on chip-based 3D ion traps. Different types of chip materials, the integration of electronic filter components on-chip and compact electrical connections in vacuum are discussed. Further, based on finite element method simulations, we discuss how integrating micro-optics in 3D ion traps is possible without disturbing the trapped 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.
