Fig. 3: Application of the resolution-enhancement ideas to a realistic setup.

Model objects (a, c), imaging scheme for (n − 1)-photon coincidence conditioned by detecting a photon in the region Ω (e), and simulation results (b, d). Sets of semitransparent slits with transmission amplitudes 0.5 ÷ 1 (a) and 0.9 ÷ 1 (c) were used as model objects. The signal (G⁽ⁿ⁾—dotted lines, G⁽ⁿ⁻¹⁾—dashed lines, G^(n−1, 1)—solid lines) was simulated for the object from panel a, \({k}_{\max }d=1\), and n = 3 (b) and 4 (d). The detection region for the nth photon is \({{\Omega }}=\{{{{\bf{k}}}}:{k}_{\max }\le | {{{\bf{k}}}}| \le 2{k}_{\max }\}\). The axis x is directed across the slits. The coordinate x is normalized by the slit size d indicated in plot a.
