From: Experimental on-demand recovery of entanglement by local operations within non-Markovian dynamics

Closed-loop results.
Entanglement of formation Ef as a function of (a) the environment rotation parameter p, (b) the measurement basis angle θ. Symbols: experimental data points, continuous line: theoretical calculations for a Bell state, dotted (dashed) lines: simulations for a state with a fidelity F = 0.90 (F = 0.95) to a Bell state. The black colour corresponds to the uncontrolled dynamics and the violet/pink colours to the corrected dynamics. The error bars determination is given in the Methods.
