论文摘要
我们研究了氮化氮化氮化物超导的性能Coplanar波导谐振器朝着具有镁光子偶联的混合量子设备的性能。我们发现内部质量因子〜20000在20 MK基础温度下，在零磁场中。我们发现，通过将薄膜厚度降低到100 nm以下的内部质量因子以下，大于1000，可以维持到〜1 t的平行磁场，垂直磁场的平行磁场和〜100 mt的垂直磁场。我们进一步证明了这些谐振器中微波光子的强耦合，镁在三氯化铬（van deraals）中，van deraals抗fiferromagnet，这表明这些空腔是研究基于2D镁基于2D Magnonics Hybrid量子量子系统的镁磷脂偶联的良好平台。我们证明了抗铁磁铁的光学和声学镁模式的强镁偶联耦合。
We investigate the performance of niobium nitride superconducting coplanar waveguide resonators towards hybrid quantum devices with magnon-photon coupling. We find internal quality factors ~ 20000 at 20 mK base temperature, in zero magnetic field. We find that by reducing film thickness below 100 nm internal quality factor greater than 1000 can be maintained up to parallel magnetic field of ~ 1 T and perpendicular magnetic field of ~ 100 mT. We further demonstrate strong coupling of microwave photons in these resonators, with magnons in chromium trichloride, a van der Waals antiferromagnet, which shows that these cavities serve as a good platform for studying magnon-photon coupling in 2D magnonics based hybrid quantum systems. We demonstrate strong magnon-photon coupling for both optical and acoustic magnon modes of an antiferromagnet.
