| 为深入探讨直接互惠和量子纠缠如何影响合作的演化，运用演化博弈理论的方法建立
了直接互惠下量子囚徒困境模型，计算博弈动态的均衡点并对均衡点进行稳定性分析，讨论直接
互惠参数和纠缠对均衡点的影响。分析结果表明，当直接互惠参数、量子纠缠在不同条件下，合作
策略和背叛策略为演化稳定策略，并且当纠缠大于临界值时直接互惠行为促进合作；纠缠小于临
界值时直接互惠行为抑制合作。最后通过数值仿真验证了理论的正确性。 |
| 英文摘要: |
| In order to explore how direct reciprocity and entanglement affect the evolution of cooperation, a quantum pris⁃
oner′s dilemma model under direct reciprocity is established by using the method of evolutionary game theory. The equilib⁃
rium points of the game dynamics are calculated and the stability of the equilibrium points is analyzed. The influences of di⁃
rect reciprocity parameters and entanglement on the equilibrium points are discussed. The results show that when the direct
reciprocity parameter and the quantum entanglement are different, the cooperation strategy and the betrayal strategy are
evolutionarily stable, and when the entanglement is greater than the critical value, the direct reciprocity behavior promotes
cooperation. When entanglement is less than critical value, direct reciprocal behavior inhibits cooperation. Finally, the cor⁃
rectness of the theory is verified by numerical simulation. |
