论文摘要
我们演示了微波介导的远处磁通磁通耦合在超导电路平台上，并结合了芯片安装的单晶y $ _3 $ fe $ _5 $ _5 $ o $ $ _ {12} $（yig）球。证明了两个YIG球体的磁杆模式之间的相干水平排斥和耗散水平的吸引力。前者是由超导谐振器的空腔光子介导的，后者是通过传播共面波导的光子介导的。我们的结果为探索集成的混合磁通网络开辟了新的途径，以在量子兼容的超导平台上进行连贯的信息处理。
We demonstrate microwave-mediated distant magnon-magnon coupling on a superconducting circuit platform, incorporating chip-mounted single-crystal Y$_3$Fe$_5$O$_{12}$ (YIG) spheres. Coherent level repulsion and dissipative level attraction between the magnon modes of the two YIG spheres are demonstrated. The former is mediated by cavity photons of a superconducting resonator, and the latter is mediated by propagating photons of a coplanar waveguide. Our results open new avenues towards exploring integrated hybrid magnonic networks for coherent information processing on a quantum-compatible superconducting platform.
