Coherent and dissipative interactions between different quantum systems are essential for the construction of hybrid quantum systems and the investigation of novel quantum phenomena. Here, we propose and analyze a magnon-skyrmion hybrid quantum system, consisting of a micromagnet and nearby magnetic skyrmions. We predict a strong-coupling mechanism between the magnonic mode of the micromagnet and the quantized helicity degree of freedom of the skyrmion. We show that with this hybrid setup it is possible to induce magnon-mediated nonreciprocal interactions and responses between distant skyrmion qubits or between skyrmion qubits and other quantum systems like superconducting qubits. This work provides a quantum platform for the investigation of diverse quantum effects and quantum information processing with magnetic microstructures.

磁振子-斯格明子混合量子系统：通过磁振子定制相互作用

不同量子系统之间的相干和耗散相互作用对于构建混合量子系统和研究新的量子现象至关重要。在这里，我们提出并分析了一种磁子-斯格明子混合量子系统，由微磁体和附近的磁性斯格明子组成。我们预测了微磁体的磁振模和斯格明子的量子化螺旋自由度之间的强耦合机制。我们证明，通过这种混合设置，可以在遥远的斯格明子量子位之间或斯格明子量子位与其他量子系统（如超导量子位）之间诱导磁振子介导的非互易相互作用和响应。这项工作为研究各种量子效应和磁性微结构的量子信息处理提供了一个量子平台。
