Figure 2: The correlation dynamics of input state (5) with b=0.75.
From: Experimental investigation of classical and quantum correlations under decoherence

(a) The values of conditional entropy S(ρlA), with photons evolving in different thicknesses of quartz plates (L), as a function of the measurement angle θ in mode B. (b) The dynamics of correlations. Green upward-pointing triangles, black squares, red dots, blue stars and magenta downward-pointing triangles represent experimental results of I, C, Q, En and Rn, with the green solid line, black solid line, red dashed line, blue dotted line and magenta dotted line representing the corresponding theoretical predictions. Non-entanglement quantum correlation (D) is further compared with C in the inset (the x axis represents the total thickness of quartz plates and the y axis denotes different kinds of correlations). Purple dots represent the experimental results of D and the purple dotted line is the corresponding theoretical prediction. Error bars correspond to counting statistics. λ0=0.78 μm.
