The initial input state ρabin has λ+=0.9. The black solid line, dashed red line, dot-dashed blue line and dotted dark cyan line represent, respectively, the theoretical predictions of total , classical , quantum correlations and concurrence C (the value is set to 0 when Γ<0, which is represented by the solid dark cyan line). The black, red, blue and dark cyan dots represent the corresponding experimental results. (a) The dynamics of correlations in the coherent evolution. Only the SBC is used in the experimental setup and the relative phase (in units of π) is =ω0τ. Revivals of entanglement and of quantum correlations are clearly noticed. (b) The maximum of the correlations is plotted as a function of the QP length L (in units of λ0=800 nm, that is the center photon wavelength). The coherent evolution, including oscillations and revivals, in a is a part of the decoherent evolution in b, which is denoted by the red box in b. The inset of b shows the theoretical dynamics of the various kinds of correlations with a calculation precision set to 0.1λ0. Error bars are due to the counting statistics.
