From: A novel framework of classical and quantum prisoner’s dilemma games on coupled networks

The stationary fraction of super cooperators (Q) as a function of b in the evolutionary QPD on network G2 under different α, given that the entanglement degree γ takes different values.
(a–f) correspond to results of γ being 0.0 ∗ π/2, 0.2 ∗ π/2, 0.4 ∗ π/2, 0.6 ∗ π/2, 0.8 ∗ π/2, 1.0 ∗ π/2, respectively. Each data presented is the average of 100 realizations.
