We numerically and experimentally demonstrate the utilization of the synchronization of chaotic lasers for decision making. We perform decision making to solve the multi-armed bandit problem using lag synchronization of chaos in mutually coupled semiconductor lasers. We observe the spontaneous exchanges of the leader-laggard relationship under lag synchronization of chaos, and we find that the leader laser can be controlled by changing the coupling strengths between the two lasers. To solve the multi-armed bandit problem, we select one of the slot machines with unknown hit probabilities based only on the identity of the leader laser while reconfiguring the coupling strength to determine the correct decision. We successfully perform an on-line experimental demonstration of the decision making based on the two-laser coupled architecture. This is the first time that synchronization in chaotic lasers is utilized for decision making, and this study paves the way for novel resources for future photonic intelligence.
我们通过数值模拟和实验证明了混沌激光器同步在决策中的应用。我们利用相互耦合的半导体激光器中的混沌滞后同步来进行决策，以解决多臂老虎机问题。我们观察到在混沌滞后同步下领导者-跟随者关系的自发交换，并且发现通过改变两个激光器之间的耦合强度可以控制领导者激光器。为了解决多臂老虎机问题，我们仅根据领导者激光器的身份选择一台命中概率未知的老虎机，同时重新配置耦合强度以确定正确的决策。我们成功地基于双激光器耦合架构进行了决策的在线实验演示。这是首次将混沌激光器中的同步用于决策，该研究为未来光子智能的新型资源铺平了道路。
