Abstract
Giuseppe Carleo - Flatiron Institute, a Division of the Simons Foundation, Center for Computational Quantum Physics I will present applications of machine learning techniques to the realm of many-body quantum physics, discussing challenges and successes obtained in the past few years. First, I will discuss the central object to be modeled, the many-body wave function, and its parameterization in terms of artificial neural networks [1]. I will then introduced the concept of variational learning, naturally emerging in quantum physics, and in a middle ground between generative modeling and reinforcement learning. In this context, I will present recent extensions of autoregressive generative models, particularly suitable for variational learning and other tasks [2]. I will finally discuss several applications suitable for experimental data, including Quantum State Tomography of highly-entangled states [3].
