Scientists are increasingly turning to machine learning to overcome formidable challenges in quantum technology. Marin Bukov (Max Planck Institute for the Physics of Complex Systems) and Florian Marquardt (Max Planck Institute for the Science of Light, Friedrich-Alexander-Universität Erlangen-Nürnberg), alongside their colleagues, demonstrate how reinforcement learning (RL) , a powerful technique based on adaptive decision-making , can be successfully applied to optimise quantum systems. This review surveys recent advances in utilising RL for crucial tasks such as state preparation, gate design, and circuit construction, even extending to interactive capabilities like feedback control and error correction. By highlighting experimental implementations, this work showcases RL’s growing importance and outlines key areas for future research, potentially accelerating the development of practical quantum technologies.
Reinforcement learning optimises complex quantum systems
Scientists have demonstrated a powerful new approach to tackling challenges in quantum technology by leveraging reinforcement learning (RL), a form of machine learning based on adaptive decision-making through interaction with a quantum device. This breakthrough research establishes RL as a key methodology for optimising complex quantum systems, moving beyond traditional control strategies and opening doors to more efficient and robust quantum devices. The team achieved significant progress in several critical areas, including state preparation for both few- and many-body quantum systems, the design and optimisation of high-fidelity quantum gates, and the automated construction of quantum circuits applicable to variational eigensolvers and architecture search. The study reveals a comprehensive framework for applying RL to quantum systems, beginning with a concise introduction to the core concepts for a broad physics audience.
