论文摘要
将微波谐振器与稀土掺杂晶体进行连接，这是一个有希望的混合量子系统，用于应用程序，包括自旋辅助传感器和记忆。稀土离子和微波光子之间的旋转之间的耦合强度的特征是合作。在这里，我们报告了稀土旋转与平面超导微波谐振器之间的超高协作$ c \ sim $ 650，该谐振器具有高度均匀的磁场，用于利用浓度的浓度掺杂的浓度的掺杂的浓度的各向异性耦合强度。这种合作性可与大量的介电谐振器匹配，并为在集成平台上有效旋转与微波光子有效耦合。
Interfacing superconducting microwave resonator with rare earth doped crystals presents a promising hybrid quantum system for applications including spin-assisted transducers and memories. The coupling strength between spins of rare earth ions and the microwave photons is characterized by the cooperativity. Here we report an ultra-high cooperativity $C \sim$ 650 between rare earth spins and a planar superconducting microwave resonator that features a highly uniform magnetic field for harnessing the strong anisotropic coupling strength of erbium doped yttrium orthosilicate. This cooperativity rivals that from a bulk dielectric resonator and paves a path for efficiently coupling of spins with microwave photons on an integrated platform.
