AI 中文摘要
多体相互作用为生成混合量子态提供了独特途径，但其固有的弱非线性耦合限制了所得关联的可控操纵。我们表明，协同双压缩与腔Kerr非线性共同使得在三方自旋-光子-声子系统中可控地工程化Kerr滤波混合态成为可能。双压缩指数级增强自旋介导的光子-声子对生成通道，而Kerr相互作用选择性地重塑光子组分，同时维持底层三方转换过程。该机制重构了混合激发的组成，并产生了与自发$Z_{2}^{(a)}\ imes Z_{2}^{(b)}$宇称破缺相关的四重相空间流形。我们的结果揭示了一种通过结合相互作用放大与模式选择性非线性滤波来工程化混合量子态的策略。
英文摘要
Multipartite interactions provide a unique route to generate hybrid quantum states, yet their intrinsically weak nonlinear coupling limits the controllable manipulation of the resulting correlations. Here we show that cooperative double squeezing and cavity Kerr nonlinearity together enable controllable engineering of Kerr-filtered hybrid states in a tripartite spin-photon-phonon system. Double squeezing exponentially enhances the spin-mediated photon-phonon pair-generation channel, whereas the Kerr interaction selectively reshapes the photonic component while maintaining the underlying tripartite conversion process. This mechanism reconstructs the composition of the hybrid excitation and gives rise to a fourfold phase-space manifold associated with spontaneous $Z_{2}^{(a)}\times Z_{2}^{(b)}$ parity breaking. Our results reveal a strategy for engineering hybrid quantum states by combining interaction amplification with mode-selective nonlinear filtering.
