...This is consistent with the prediction that the pure s-shell resonant excitation can eliminate dephasings associated with the incoherent excitation methods [5, 6]....

...Two-photon HOM interference experiments using photons from a single QD [5, 15, 17], as well as from independent sources [18, 19], have not only demonstrated the potential of QDs as single-photon sources, but also revealed the level of dephasing arising from incoherent excitation....

...2c) should also happen at a time scale much longer than the 2-ns separation, which is consistent with previous experiments [5, 7, 15, 40]....

...If two perfectly indistinguishable photons are superposed on a beam splitter, they will always exit the beam splitter together through the same output port, leading to a zero coincidence rate—the HOM dip [5] which cannot explained by classical optics....

...These proposals primarily rely upon a high degree of indistinguishability between individual photons to obtain the Hong-Ou-Mandel (HOM) type interference [5] which is at the heart of photonic controlled logic gates and photon-interference-mediated quantum networking [1–4]....
