从非全同人工分子中最佳产生不可分辨光子
Optimal generation of indistinguishable photons from non-identical artificial molecules
摘要：
我们从理论上表明，几乎无法区分的光子可以产生与不相同的基于光子的源。虚拟拉曼跃迁的使用和外部驱动场的优化增加了对meV能量范围的光谱不均匀性的容限。在光子产生过程中，在光子不可逆性和效率之间出现权衡。线性（二次）的符合概率内的洪-欧-曼德尔设置被发现相对于在半导体源的退相（弛豫）率。
英文摘要：
We show theoretically that nearly indistinguishable photons can be generated with non-identical semiconductor-based sources. The use of virtual Raman transitions and the optimization of the external driving fields increases the tolerance to spectral inhomogeneity to the meV energy range. A trade-off emerges between photon indistinguishability and efficiency in the photon-generation process. Linear (quadratic) dependence of the coincidence probability within the Hong-Ou-Mandel setup is found with respect to the dephasing (relaxation) rate in the semiconductor sources.
