我们提出了一个离子捕获和超导量子比特系统的实验集成的设计，作为实现量子混合系统的一步。该方案解决了实现这样一个系统的两个关键困难：一个组合的微制造离子阱和超导量子位架构，以及促进这两种技术的实验基础设施。基于Kielpinski等人的工作（Phys Rev Lett 108（13）：130504，. doi：10.1103/PhysRevLett.108.130504），我们描述了一种微制造离子阱的设计、模拟和制造过程，该离子阱能够将离子耦合到具有数十kHz耦合强度的超导微波LC电路。我们还描述了现有的困难，结合离子捕获设置到稀释制冷机与超导量子位的实验基础设施和目前的解决方案，可以立即实施使用当前的技术。
We present a design for the experimental integration of ion trapping and superconducting qubit systems as a step towards the realization of a quantum hybrid system. The scheme addresses two key difficulties in realizing such a system: a combined microfabricated ion trap and superconducting qubit architecture, and the experimental infrastructure to facilitate both technologies. Developing upon work by Kielpinski et al. (Phys Rev Lett 108(13):130504,. doi:10.1103/PhysRevLett.108.130504), we describe the design, simulation and fabrication process for a microfabricated ion trap capable of coupling an ion to a superconducting microwave LC circuit with a coupling strength in the tens of kHz. We also describe existing difficulties in combining the experimental infrastructure of an ion trapping set-up into a dilution refrigerator with superconducting qubits and present solutions that can be immediately implemented using current technology.
