摘要
Magnons,the collective excitation of magnetically ordered materials,have attracted considerable interest for their low energy consumption,long coherence time and useful working 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 information and satisfy the requirement of building perfect quantum information networks[2].The emergying field cavity spintronics has inspired many interesting physics like nonreciprocal microwave propagation and energy level attraction,together with quite a few applications such as magnon sensors and magnon-photon transducers.
