Photonic Computing Highlighting Ultimate Nature of Light: Decision Making by Photonics

Abstract

Decision making is important in information and communications technology and artificial intelligence. Here, we present photonics approaches to realize decision making using classical and quantum light. We demonstrate a single-photon-based system to solve multi-armed bandit problems by utilizing wave-particle duality for exploration. The principle is applied to chaotic lasers where the chaotically oscillating time series provides fast and scalable decision-making abilities. Furthermore, we demonstrate the usefulness of quantum interference effects in social decision-making, whereby the expected value regards maximization of social benefits and ensuring fairness among individuals. The impact of near-field optics for computing is also discussed.
