By considering two qubit ensembles that are nonuniformly coupled to a common resonator,他们有效地抑制了相互作用中的非谐振贡献,他们实现周期调制量子系统中两个Dicke态的纠缠, by utilizing the Holstein-Primakoff transformation, we can obtain ensemble-ensemble entangled states by performing a projective even-odd cat-state measurement. By implementing Gaussian soft temporal modulation,imToken, we propose a scheme of creating magnon NOON states through frequency modulation and study the influence of decoherence on the fidelity of target states.
