(a) Storage process for a quantum state |ψ_s〉 = α_F|ψ₀〉 + β_F|ψ₁〉. (b) Retrieval process. In both cases, we plot the fidelity between the initial |ψ〉_s and the instantaneous state |ψ(t)〉, i.e., , while we introduce external noises Γ_x = Γ_y = Γ_z = 10⁻³ω_eg and Γ_r = 10⁻⁴ω_eg into our close system with the help of the microscopic derivation⁴⁰. Here, Γ_x, Γ_y, Γ_z and Γ_r are rates of bit-flip noises, dephasing noise of the qubit, and the resonator relaxation, respectively. The system parameters are ω_cav = 1, ω_eg = 0.1 ω_cav, Ω₀ = ω_cav, and the total evolution time is T = 105/ω_cav.
