Probabilities of emitting one, two, and more photons versus evolution time t , with the detuning frequency Δ A = Δ ω /2. Panels (a), (b), and (c) correspond to the Rabi frequencies Ω A = Ω B = 50, 100, and 150 MHz, respectively. The other parameters are the same as those in Fig.  1 . The solid lines correspond to the probabilities of emitting one photon P 1( t ), dashed lines correspond to the probabilities of emitting two photons P 2( t ), and the dash-dotted lines correspond to the probabilities of emitting multi- photon P multi( t ) = 1 − P 0( t ) − P 1( t ) − P 2( t ).
