摘要:

在这项工作中,我们从理论上研究了单分子磁体(SMM)的耦合到各种量子线路,包括微波谐振器和没有压缩和通量量子比特。这项研究的主要结果是,SMM晶体和超导电路之间可以实现强耦合和超强耦合,强烈暗示这种耦合也可以达到接近收缩的单个分子。基于这些分子的耦合强度和典型的相干时间(微秒级),我们得出结论,SMM可以用于相干存储和操作的量子信息,无论是在量子计算的背景下,还是在量子模拟。在整个工作中,我们还详细讨论了最适合这种操作的分子家族,不仅基于耦合强度,而且基于典型的能隙和简单性,它们可以被调谐和定向。最后,我们还讨论了SMMs的实际优势,如通过沉积小液滴在芯片上制造SMMs集成的可能性。

英文摘要:

In this work we study theoretically the coupling of single molecule magnets (SMMs) to a variety of quantum circuits, including microwave resonators with and without constrictions and flux qubits. The main results of this study is that it is possible to achieve strong and ultrastrong coupling regimes between SMM crystals and the superconducting circuit, with strong hints that such a coupling could also be reached for individual molecules close to constrictions. Building on the resulting coupling strengths and the typical coherence times of these molecules (of the order of microseconds), we conclude that SMMs can be used for coherent storage and manipulation of quantum information, either in the context of quantum computing or in quantum simulations. Throughout the work we also discuss in detail the family of molecules that are most suitable for such operations, based not only on the coupling strength, but also on the typical energy gaps and the simplicity with which they can be tuned and oriented. Finally, we also discuss practical advantages of SMMs, such as the possibility to fabricate the SMMs ensembles on the chip through the deposition of small droplets.
