本研究揭示在三部分Mollow系统中，耗散通道对称性可选择性调控量子发射路径，对称耗散产生强相关光子-声子对，不对称耗散则产生高纯度光子束，为可编程混合量子发射器提供新途径。
AI 中文摘要
耗散通常被认为对非经典态的产生有害，然而它能否决定开放混合量子系统发射何种量子资源，在很大程度上仍未得到探索。在此，我们证明玻色子耗散通道的对称性可以在三部分Mollow系统中选择和切换量子发射路径，其中强驱动的二能级发射体同时耦合到腔光子和运动声子。在Mollow regime中，高阶三部分相互作用产生共振光子-声子对激发，其发射的量子态随后由耗散选择。在对称耗散下，系统产生强相关的光子-声子对，实现单对发射和具有显著非经典相关性的相关多对束。打破耗散对称性会逐渐抑制混合相关性，并动态解耦光子和声子自由度。在强不对称区域，长寿命声子在高激发Fock态中积累，而快速泄漏的腔光子被转换为高纯度单光子和双光子束。这些不同发射区域之间的交叉通过时间分辨相关函数、Fock态分布和Wigner准概率分布来表征。我们的结果确立了耗散对称性作为在混合和纯光子非经典态之间引导量子发射的资源，为可编程混合量子发射体和耗散量子态工程提供了途径。
英文摘要
Dissipation is generally regarded as detrimental to nonclassical-state generation, yet whether it can determine which quantum resource is emitted from an open hybrid quantum system remains largely unexplored. Here, we show that the symmetry of bosonic dissipation channels can select and switch quantum-emission pathways in a tripartite Mollow system, where a strongly driven two-level emitter simultaneously couples to cavity photons and motional phonons. In the Mollow regime, higher-order tripartite interactions generate resonant photon-phonon pair excitations, whose emitted quantum states are subsequently selected by dissipation. Under symmetric dissipation, the system produces strongly correlated photon-phonon pairs, enabling both single-pair emission and correlated multipair bundles with pronounced nonclassical correlations. Breaking the dissipation symmetry progressively suppresses the hybrid correlations and dynamically decouples the photonic and phononic degrees of freedom. In the strongly asymmetric regime, long-lived phonons accumulate in highly excited Fock states, while rapidly leaking cavity photons are converted into high-purity single-photon and two-photon bundles. The crossover between these distinct emission regimes is characterized through time-resolved correlation functions, Fock-state distributions, and Wigner quasiprobability distributions. Our results establish dissipation symmetry as a resource for steering quantum emission between hybrid and purely photonic nonclassical states, providing a route toward programmable hybrid quantum emitters and dissipative quantum-state engineering.
