(a) The fidelity of the target steady state as a function of the Rabi frequencies Ω 1 and Ω 2 with the initial state | gg , 00 〉 at time 1 × 10 4 / g . (b) The fidelity of the target steady state versus the variance of the single-photon decay κ and qubit decay γ at time 1 × 10 4 / g . (c) The fidelity of the target steady state versus photon hopping rate J and evolution time. The rest of the parameters are the same as those in Fig. 4.
