The file 'dot_spectrum.dat' contains the spectrum of the quantum dot being used, without monochromating filter, as shown in Fig. 1. The file 'dot_cohtime_+1V.dat' contains the Mach Zehnder interference information for the quantum dot line used, under the experimental conditions, shown in Fig. 2(a). The files 'X_cohtime_vs_bias.dat' and 'Xch_cohtime_vs_bias.dat' contain data on the dependence on the neutral (X) and charged (Xch/X*) exciton lines' coherence times with applied bias voltage, as shown in Fig. 2(b). The file 'TPI_data.dat' contains the data for the second-order correlations of co- and cross-polarised dot/laser beams, as shown in Fig. 4.
