纳米结构物质（如量子点）之间的光学近场相互作用导致能量耗散时的单向光激发转移。这导致在通用的时空动力学的光激发，这可以通过工程控制的耗散过程，并利用实现智能功能，如解决方案搜索和决策。在这里，我们通过实验证明了通过使用不同大小的胶体量子点，形成在几何形状控制的基板上的近场相互作用的光激发转移的基础上解决决策问题的能力。我们描述了由于多个控制光模式的能量转移行为，并通过实验证明了解决多臂强盗问题的能力。我们的工作朝着能够有效决策的纳米光子系统的实际设计迈出了决定性的一步，这是人类大脑最重要的智力属性之一。(C)2014 AIP出版有限责任公司。
Optical near-field interactions between nanostructured matters, such as quantum dots, result in unidirectional optical excitation transfer when energy dissipation is induced. This results in versatile spatiotemporal dynamics of the optical excitation, which can be controlled by engineering the dissipation processes and exploited to realize intelligent capabilities such as solution searching and decision making. Here, we experimentally demonstrate the ability to solve a decision making problem on the basis of optical excitation transfer via near-field interactions by using colloidal quantum dots of different sizes, formed on a geometry-controlled substrate. We characterize the energy transfer behavior due to multiple control light patterns and experimentally demonstrate the ability to solve the multi-armed bandit problem. Our work makes a decisive step towards the practical design of nanophotonic systems capable of efficient decision making, one of the most important intellectual attributes of the human brain.
