Populations of | T , 00 , | S , 00 , | gg , 00 , | ff , 00 corresponding to four channels in Fig. 2 with the initial state | gg , 00 . The optimized parameters are chosen as (a) Ω 1 = 0.066 g , Ω 2 = 0.02 g , J = 1.2 g , κ = γ = 0.022 g , γ ϕ = 6.8 × 10 5 g , and ω 1 = ω e J 2 + g 2 . (b) Ω 1 = 0.026 g , Ω 2 = 0.02 g , J = 1.1g, κ = γ = 0.01 g , γ ϕ = 6.8 × 10 5 g , and ω 1 = ω e . (c) Ω 1 = 0.065 g , Ω 2 = 0.012 g , J = 1.5g, κ = 0.008g, γ = 0.01 g , γ ϕ = 6.8 × 10 5 g , and ω 1 = ω e + J 2 + 4 g 2 / 2 J / 2 . (d) Ω 1 = 0.063 g , Ω 2 = 0.012 g , J = 0.8 g , κ = 0.0008 g , γ = 0.012 g , γ ϕ = 6.8 × 10 5 g , and ω 1 = ω e J 2 + 4 g 2 / 2 J / 2 .
