Fig. 6: Results for distillation of Gaussian steering with a correlated noisy channel and measurement-based NLA.
From: Sudden death and revival of Gaussian Einstein–Podolsky–Rosen steering in noisy channels
Black solid and dash curves are the theoretical predicted steerabilities in a noisy channel with excess noise five times of vacuum noise. Red solid and dash curves are the predicted steerabilities after revival of Gaussian steering with a correlated noisy channel. The orange and purple curves are the predicted steerabilities when the measurement-based NLA based on Bob’s measurement results with gain of 1.2 is applied before and after the revival of Gaussian steering, respectively. The blue solid and dash curves are the predicted steerabilities in a pure lossy but noiseless channel.
