摘要

Magnons,the collective excitation of magnetically ordered materials,have attracted considerable interest for their low energy consumption,long coherence time and useful work-ing frequency from gigahertz to terahertz.Besides,magnons can coherently interact with phonons,microwave and optical photons,as well as superconducting qubits,as schematically depicted in Figure 1,providing a novel platform to achieve hybrid quantum systems[1].Hybridizing distinct quantum systems with multitasking capabilities is critical in quantum information processing,because a single quantum system cannot keep pace with the fast development of quantum infor-mation and satisfy the requirement of building perfect quan-tum information networks[2].The emergying field cavity spintronics has inspired many interesting physics like nonre-ciprocal microwave propagation and energy level attraction,together with quite a few applications such as magnon sen-sors and magnon-photon transducers.
