The initial second-order correlation,${\mathit{g}}_{\mathbf{2}}\mathbf{(}\mathbf{0}\mathbf{)}$(on a logarithmic scale), calculated with a weak incident coherent state as a function of the single-photon transmission probability, T , for different numbers of qubits. The first (second) row is for $k_{0}L=\pi /2$ ($\pi /4$); the first (second) column is for transmitted (reflected) photons. For reflected photons with $N=1$, $g_2(0)=0$ for all T and hence is not plotted. For a wide range of parameters, both transmitted and reflected photons are bunched.
