论文摘要
我们演示了一个由有机基的Ferrimagnet钒四酰基乙烯（V [TCNE] $ _ x $）组成的由有机基于有机的Ferrimagnet Vanadium Tetrymagnet餐厅托管的混合量子系统。我们的工作是由将任意形状的低阻尼磁系统与平面超导电路相结合的挑战所激发的，从而实现了以前无法访问的大量量子宏伟的电路设计。例如，通过利用木元素的固有特性，可以启用使用镁传播而不是电流的非磁磁介导的量子设备。我们可以利用具有超低固有阻尼的V [tcne] $ _ x $的特性，可以在较低的加工温度下在任意底物上生长，并且可以通过电子束光刻图案进行图案。我们演示了由薄膜超导谐振器组成的混合量子宏伟设备的可扩展的，线石化的制造，并与低阻尼，薄膜V [tcne] $ _ x $ _ x $显微结构耦合。我们的设备在强耦合方面运行，在T $ \ sim $ 0.4 K时，合作性高达1181（44），适用于可扩展的量子电路集成。这项工作为探索高共振性混合型量子设备铺平了道路，其中可以像电线一样轻松地设计和制造岩石电路。
We demonstrate a hybrid quantum system composed of superconducting resonator photons and magnons hosted by the organic-based ferrimagnet vanadium tetracyanoethylene (V[TCNE]$_x$). Our work is motivated by the challenge of scalably integrating an arbitrarily-shaped, low-damping magnetic system with planar superconducting circuits, thus enabling a host of quantum magnonic circuit designs that were previously inaccessible. For example, by leveraging the inherent properties of magnons, one can enable nonreciprocal magnon-mediated quantum devices that use magnon propagation rather than electrical current. We take advantage of the properties of V[TCNE]$_x$, which has ultra-low intrinsic damping, can be grown at low processing temperatures on arbitrary substrates, and can be patterned via electron beam lithography. We demonstrate the scalable, lithographically integrated fabrication of hybrid quantum magnonic devices consisting of a thin-film superconducting resonator coupled to a low-damping, thin-film V[TCNE]$_x$ microstructure. Our devices operate in the strong coupling regime, with a cooperativity as high as 1181(44) at T$\sim$0.4 K, suitable for scalable quantum circuit integration. This work paves the way for the exploration of high-cooperativity hybrid magnonic quantum devices in which magnonic circuits can be designed and fabricated as easily as electrical wires.
