Fig. present the incorrect dynamics when the random phases θ ξ (in Eq. 69b) are intentionally ignored by setting them to be zero. One can see that the diagonal populations of states |1⟩ and |0⟩ still show the correct exponential decay/growth, but the coherences take a large departure from the expected coherences because there is no random phase present to correct the artificial coherence that is produced when the magnitudes of the coefficients are changed.
