The emission intensity I (a) and the Mandel's Q parameter (b) versus time t . The red lines represent the emission intensity and the Mandel's Q parameter of the parallel system, the blue lines represent that of the orthogonal system. The average Rabi frequencies Ω 12 = Ω 13 = 0, 𝓦 12 = 𝓦 13 = 𝓦 23 = Γ , the green lines represent the reference lines corresponding to 𝓦 23 = 0, which represent the case with no quantum beats have occurred and the system is in the ground state.
