Coherence C 
of the qubit as a function of the scaled time Γ1t for different values of the detuning δ in the case when the cavity C2 is perfect, that is Γ2 = 0.
The qubit-C1 and the C1-C2 coupling strengths are, respectively, (a) κ = 0.24 Γ1, J = 0.3 Γ1; (b) κ = 0.4 Γ1, J = 0.3 Γ1. Out of resonance (δ > 0) no coherence trapping is achievable.
