(a) the fidelity versus γ_ϕ/g in the coupled cavity system, and the related parameters used for state transfer and entangled state preparation are the same as those used in Fig. 5; (b) the fidelity versus γ_ϕ/g in the cavity–fiber–cavity system, and the related parameters used for state transfer and entangled state preparation are the same as those used in Fig. 9. In the figure above, S and E represent the state transfer and the preparation of entangled states, respectively.
