Zhang Zijing^{1, †}, Wang Feng², Song Jie¹, Zhao Yuan¹

Coincidence probability distribution of 10-step two-photon quantum random walk with tunable beam splitters of (a) σ_BS = 0, (c) σ_BS = 0.1, (e) σ_BS = 0.2, (g) σ_BS = 0.3, (i) σ_BS = 0.4. Panels (b), (d), (f), (h), (j) are photon distributions of panels (a), (c), (e), (g), (i), respectively.
