a–c The recorded coincidence counts against the EOM phase with a step of π/4. The red curves are fitted by \(N[\xi | \sqrt{1-{\eta }_{1{\rm{con}}}}\sqrt{{\eta }_{2}}+\sqrt{{\eta }_{1}}{e}^{i{\varphi }_{{\rm{EOM}}}}{| }^{2}+(1-\xi ){\eta }_{1}]\), N is the total photon counts N = 650 ± 10, η1 = 0.151 ± 0.002, η1con = 0.874 ± 0.011, η2 = 0.247 ± 0.005. The fitted ξ is 0.001, 0.530, 0.960 for (a)–(c) respectively. The error bars denote one standard deviation. d Simulated result of wave-like, particle-like behaviors and intermediate situations as a function of ξ with N = 650, η1 = 0.151, η1con = 0.874, η2 = 0.247.
