High-NOON States with High Flux of Photons Using Coherent Beam Stimulated Noncollinear Parametric Down Conversion

Figure 3

(a) The setup for mixing laser and noncollinear PDC lights at a BS. There are six distinct ways to mix laser and PDC photons leading to 3-NOON state: (b) No photons from PDC, 3 photons from upper laser, no photons from lower laser, and vice versa. (c) No photons from PDC, 2 photons from upper laser, 1 photon from lower laser, and vice versa. (d) 2 photons from PDC, 1 photon from upper laser, no photons from lower laser, and vice versa. Compare this to Figures 1(b), 1(c).
