(a) Contour plots of the fidelity between the state and the state |ψ(t)〉, which has adiabatically evolved from the initial state |ψ_s〉 = α_F|ψ₀〉 + β_F|ψ₁〉, when the total evolution time is set to T = 105/ω_cav, and (b) when the evolution time is T = 120/ω_cav. For the above cases, the black lines stand for the phase which maximized the fidelity . In these simulations, the parameters are ω_cav = 1, ω_eg = 0.1 ω_cav, and Ω₀ = ω_cav. (c) Storage process for an entangled state . (d) Retrieval process. In both cases, we plot the fidelity between the initial state |Ψ₀〉, and the instantaneous state |ψ(t)〉, . In the simulations (c) and (d), we have chosen ω_cav = 1, ω_eg = 0.1 ω_cav, Ω₀ = ω_cav, and the evolution time T = 105/ω_cav.
