Reinforcement learning to control quantum matter out of equilibrium

The ability to manipulate quantum matter in equilibrium is a fundamental achievement of 20th century physics. The main objective of modern physics is to extend this knowledge so as to cover systems out of equilibrium. Being at the border of equilibrium and non-equilibrium, the periodically driven (“Flockè”) systems are particularly suitable for this purpose. Based on the periodic drives, experiments with ultracold atoms may reproduce such phenomena currently unavailable in conventional materials, such as artificial calibration fields or topological and dynamically localised matter. Our knowledge of how to manipulate systems exposed to intensive periodic drives is at an early stage, especially with regard to highly interacting systems. We propose to overcome current limitations by combining artificial intelligence algorithms with ideas taken from statistical physics and quantum control. We will develop a new theoretical framework for non-adiabatic control of the quantum state of many bodies subjected to strong periodic drives, which is used as the basis for optimal scrambling, weaving, heating and cooling of quantum states. Understanding the dynamic properties of multi-body systems will improve the state-of-the-art techniques to manipulate cold atoms, optically trapped ions, superconducting qubits, and quantum solids. The quantum control toolkit we will be accompanied by reinforcement learning – one of the most promising techniques in the field of artificial intelligence. Deep reinforcement learning is extremely suitable to manipulate non-equilibrium states, since it is able to identify effective macroscopic degrees of freedom, even when solutions on microscopic equations of motion are not available. The discovery of physical principles of non-equilibrium control has the potential to reveal new relationships between quantum dynamics, statistical mechanics, optimal control, and machine learning. Our proposal establishes a roadmap for creation of future materials and technologies based on non-equilibrium processes in condensed matter physics, quantum optics and quantum calculations.
