The evolution of quantum entanglement state (|Φ(0)〉AB=(1/2|00〉+1/2|11〉)AB) by different intensity weak measurements (η = 0,0.3,0.5,0.7). The full line shows the evolution of the parameter η = 0. The imaginary line displays the evolution of the parameter η = 0.3. The dotted line and dot-dashed lines reveal the evolutions of η = 0.5 and η = 0.7.
