人造磁性分子可以通过（a）集成多个量子资源和（b）降低某些应用的计算成本，为大规模量子计算的进展做出贡献。在理论建议的指导下，化学设计允许在每个分子单元中嵌入重要的量子功能，然后该分子单元充当微观量子处理器，能够对受错误保护的逻辑量子位进行编码或实现量子模拟。进一步扩大规模需要“连接”多个分子。我们讨论如何通过与片上超导谐振器的耦合来实现这一目标。我们对这种混合方法的潜在优势和仍然面临的挑战进行了严格的审查。
Artificial magnetic molecules can contribute to progressing toward large scale quantum computation by (a) integrating multiple quantum resources and (b) reducing the computational costs of some applications. Chemical design, guided by theoretical proposals, allows embedding nontrivial quantum functionalities in each molecular unit, which then acts as a microscopic quantum processor able to encode error protected logical qubits or to implement quantum simulations. Scaling up even further requires "wiring-up" multiple molecules. We discuss how to achieve this goal by the coupling to on-chip superconducting resonators. The potential advantages of this hybrid approach and the challenges that still lay ahead are critically reviewed.
