随着实验性量子信息处理（QIP）迅速发展，一个新出现的挑战是设计一种可扩展的架构，该架构能将各种量子元件组合成一个复杂的设备，同时不影响其性能。特别是，超导量子电路已成功展示了量子计算的许多要求，包括接近可扩展阈值的相干水平。然而，通过可控通道耦合大量电路元件，同时抑制任何其他相互作用，仍然具有挑战性。我们提出一个旨在应对这些挑战的硬件平台，它结合了集成电路制造的优势以及在三维电路量子电动力学中可实现的长相干时间。这种多层微波集成量子电路平台为实现日益复杂的超导设备以追求可扩展的量子计算机提供了一条途径。
As experimental quantum information processing (QIP) rapidly advances, an emerging challenge is to design a scalable architecture that combines various quantum elements into a complex device without compromising their performance. In particular, superconducting quantum circuits have successfully demonstrated many of the requirements for quantum computing, including coherence levels that approach the thresholds for scaling. However, it remains challenging to couple a large number of circuit components through controllable channels while suppressing any other interactions. We propose a hardware platform intended to address these challenges, which combines the advantages of integrated circuit fabrication and the long coherence times achievable in three-dimensional circuit quantum electrodynamics. This multilayer microwave integrated quantum circuit platform provides a path towards the realisation of increasingly complex superconducting devices in pursuit of a scalable quantum computer.
