Figure 7
Contour plots of the coarse grained coincidence counts (44) associated with the BP state for the modified HOM interferometer for different values of the asymmetry loss parameter \({\eta }_{{{\bf{B}}}_{1}{{\bf{B}}}_{2}}\) of Eq. (46). As usual for the BP configuration we assume the Gaussian frequency amplitude with ΔΩ+ = ΔΩ−/5, while the coincidence counts have been rescaled by their plateau value \(4{A}_{{\rm{BP}}}^{{\rm{loss}}}\).
