Fig. 2: Comparison between mixed-state and pure-state concurrence percolation.
From: A counter-intuitive low entanglement percolation threshold in mixed-state quantum networks
The concurrence of each link, c, and the sponge-crossing concurrence, CSC, are plotted on the x-axis and y-axis, respectively. The gray solid and dashed vertical lines mark the thresholds for mixed-state and pure-state concurrence percolation, respectively. a Bethe lattice with degree k = 3. The blue and orange curves represent the mixed-state and pure-state sponge-crossing concurrences CSC. The dashed orange line is unphysical. b, c 2D square and honeycomb lattices. The solid line connecting the circles represents the mixed-state CSC, while the dashed line connecting the triangles represents the pure-state CSC. Here L denotes the side length of the 2D lattices.
