Extended Data Fig. 5: Results of the additional rounds of TPQI experiments.
a-c, Second-order cross-correlation functions and time-delay dependent visibilities for additional round #1 (a), round #2 (b), and round #3 (c). Upper panels represent \({g}_{{\rm{HOM}}}^{(2)}\left(\tau \right)\) (as in Fig. 4d), middle panels represent \({g}_{{\rm{HOM}},{\rm{d}}}^{(2)}\left(\tau \right)\) (as in Fig. 4g), and lower panels represent \(V\left(\tau \right)=[{g}_{{\rm{HOM}},{\rm{d}}}^{(2)}\left(\tau \right)-{g}_{{\rm{HOM}}}^{\left(2\right)}(\tau )]/{g}_{{\rm{HOM}},{\rm{d}}}^{(2)}\left(\tau \right)\) (as in Fig. 4h). For each round of experiment, we re-assemble a new DBT-doped anthracene nanosheet with the photonic circuit. For a summary of the interference visibility / photon indistinguishability values evaluated from these rounds of experiments, see Extended Data Table 1. The error bars represent uncertainty derived via error propagation from counting statistics of the raw detection events (Methods).
