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.

用分子自旋扩大量子计算的观点

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来促进大规模量子计算的发展。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非平凡的量子功能，然后充当微观量子处理器，能够编码错误保护的逻辑量子位或实现量子模拟。进一步放大需要“连接”多个分子。我们讨论如何通过耦合到片上超导谐振器来实现这一目标。对这种混合方法的潜在优势和仍面临的挑战进行了严格审查。
