Erratum: Correlation control for pure and efficiently generated heralded single photons [Phys. Rev. A 91, 013819 (2015)]

Figure 11

Figure 11 in the original paper with the labels corrected. Spectral purity-efficiency factors (PEFs) for a specific value of the spectral correlation between signal and idler. The bandwidth and waist of the pump are ${\sigma }_p=1.0\mathrm{nm}$ and $w_p=10\mu \mathrm{m}$, and the spatial-spectral correlation is present because the waist of the photons' spatial modes is $w_s=w_i=50\mu \mathrm{m}$. We plot the idler's PEF when this photon is the heralded single photon (HSP) in (a) and when the signal is the heralded single photon in (b).

Figure 12

Figure 12 in the original paper with the labels corrected. Spectral PEFs when the spectral signal-idler spectral correlation is stronger than in Fig. 11. The bandwidth and waist of the pump are ${\sigma }_p=0.1\mathrm{nm}$ and $w_p=10\mu \mathrm{m}$, and the spatial-spectral correlation is present because the waist of the photons' spatial modes is $w_s=w_i=50\mu \mathrm{m}$. We plot the idler's PEF when this photon is the HSP in (a) and when the signal is the heralded single photon in (b).
