Figure 2. (Color online) Dynamical fidelity for this photon-spin state transfer process. The parameters are set as g = λ, r = 0 the black solid line with solid spheres, r = 1 the olive solid line with solid squares, r = 3 the blue solid line with open stars, and r = 5 the orange solid line, κ1 ∼ γ ∼ 0.01g, and ${\kappa }_{\mathrm{eff}}^{S}\sim 0.1g$.
