Webpartial photon distinguishability in GBS, except for a re-cent paper38 claiming to extend their results for partial distinguishability in AABS to that in GBS. The results of Ref.38 are somewhat unsatisfactory in the sense that their results for GBS must be applied in a context simi-lar to AABS. For example, their investigation is strictly

WebThis method requires quantification of distinguishability and photon purity parameters. The photon state purity is estimated using the calculated Joint Spectral Amplitude as shown in figure 2 , taking account of the non-ideal placement of the spectral filters, from which we estimate a single source purity of 0.97.
