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, 2012. 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 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.
我们提出了一种用于离子阱和超导量子比特系统实验集成的设计方案,作为迈向实现量子混合系统的一步。该方案解决了实现此类系统的两个关键难题:一种集成的微纳加工离子阱和超导量子比特架构,以及便于两种技术应用的实验基础设施。在Kielpinski等人(《物理评论快报》108(13):130504,2012年。doi:10.1103/PhysRevLett.108.130504)工作的基础上,我们描述了一种微纳加工离子阱的设计、模拟和制造过程,该离子阱能够以几十千赫兹的耦合强度将离子与超导微波电路耦合。我们还描述了将离子阱装置的实验基础设施与超导量子比特一起集成到稀释制冷机中时现有的困难,并提出了可以立即使用当前技术实施的解决方案。
