From: Experimental recovery of quantum correlations in absence of system-environment back-action

Figure 4

The entanglement evolution, quantified by the concurrence C, of the initial maximally entangled state for the coherent case as a function of the relative phase =ω0τ (in units of π). Red dots represent the experimental results of C and the black solid line represents the corresponding theoretical prediction C=|cos|. The orange solid line represents the evolution of the trace distance rate of change σ() that is positive (signature of non-Markovianity) just when the entanglement revivals occur. The dashed dark yellow line represents the boundary 0.
