我们提出了一种方案，用于从两个空间分离的二能级发射体产生高纯度荧光双光子束，其关联激发由强驱动的辅助发射体介导。与基于玻色模的方法不同，两个目标发射体的有限激发空间本质上排除了更高激发流形，从而消除了与不希望的高激发态相关的杂质光子。我们进一步解析表征了非共振单激发态的残余布居，并表明抑制相应的泄漏可提高光子束纯度。我们的方案为构建高纯度量子光源提供了一条可行途径，在量子信息处理中具有广阔的应用前景。
英文摘要
We propose a scheme for generating high-purity fluorescence two-photon bundles from two spatially separate two-level emitters, whose correlated excitation is mediated by a strongly driven auxiliary emitter. Unlike bosonic-mode-based approaches, the finite excitation space of the two target emitters intrinsically excludes higher-excitation manifolds, and thus eliminates impurity photons associated with undesired higher-excitation states. We further analytically characterize the residual population of off-resonant single-excitation states and show that suppressing the corresponding leakage improves photon bundle purity. Our scheme offers a feasible pathway for constructing high-purity quantum light sources with promising applications in quantum information processing.
