Figure 1. The optimal behavior of one-tangle $({{ \mathcal N }}_{A({{BC}}_{{\rm{I}}})})$ of fermionic modes as a function of the strength of partial measurements p0 (left panel) and partial measurement reversal q0 (right panel) for different values of the acceleration parameter r. The degraded one-tangle due to Unruh decoherence is completely recovered for the optimal value of q0 (left panel) and p0 (right panel) in the limit of ${p}_{0}\to 1$ and ${q}_{0}\to 1$, respectively.
