我们研究了量子囚徒困境博弈中信任度对合作演化的影响。除了策略之外，参与者之间的联系也会演变。从一个无标度的交互网络开始，参与者根据收到的收益调整对邻居的信任。后者控制着战略采纳过程，而信任控制着链接的重新连接。一旦对邻居的信任度下降到零，链路就会重新连接到网络中另一个随机选择的参与者。我们发现，对于小的诱惑，背叛合作者总是占主导地位，而对于中等和强的诱惑，一个单一的量子策略能够胜过所有其他策略。一般来说，互惠信任仍然存在于亲密的关系中，并倾向于单一策略的主导地位。由于协同进化，幂律度分布转化为泊松分布。
We study the impact of adaptive degrees of trust on the evolution of cooperation in the quantum prisoner's dilemma game. In addition to the strategies, links between players are also subject to evolution. Starting with a scale-free interaction network, players adjust trust towards their neighbors based on received payoffs. The latter governs the strategy adoption process, while trust governs the rewiring of links. As soon as the degree of trust towards a neighbor drops to zero, the link is rewired to another randomly chosen player within the network. We find that for small temptations to defect cooperators always dominate, while for intermediate and strong temptations a single quantum strategy is able to outperform all other strategies. In general, reciprocal trust remains within close relationships and favors the dominance of a single strategy. Due to coevolution, the power-law degree distributions transform to Poisson distributions.
