Abstract

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 toward exploring integrated hybrid magnonic networks for coherent information processing on a quantum-compatible superconducting platform.

摘要

我们在一个包含芯片安装的单晶钇铁石榴石（Y₃Fe₅O₁₂，YIG）球体的超导电路平台上展示了微波介导的远程磁振子-磁振子耦合。证明了两个YIG球体的磁振子模式之间存在相干能级排斥和耗散能级吸引。前者由超导谐振器的腔光子介导，后者由共面波导的传播光子介导。我们的结果为探索用于量子兼容超导平台上相干信息处理的集成混合磁振子网络开辟了新途径。
