IAS Center for Quantum Technologies Seminar Series - Benchmarking Analog Quantum Simulators Based on Emergent Randomness
Abstract One of the most basic tasks to characterize analog quantum simulators is to estimate the many-body fidelity between an ideal target state and the state obtained from experiments. In this talk, the speaker will present a simple and efficient benchmarking method that requires minimal experimental control. It only requires time-evolving a quantum system under its natural ergodic dynamics, followed by measurements in a fixed local basis. At its core, the method is made possible by using a newly-discovered phenomenon that occurs in strongly interacting quantum many-body systems, namely the emergence of universal random statistics. The speaker claims the phenomenon occurs universally in a wide class of ergodic quantum systems at infinite temperature by presenting a number of evidence based on solvable models and numerical simulations. He will discuss his benchmarking protocol based on the emergent randomness, and demonstrate it both numerically for model systems and experimentally using a Rydberg quantum simulator. About the speaker Prof. Choi Soonwon obtained his BS in Physics from the California Institute of Technology in 2012 and his PhD in Physics from the Harvard University in 2018. He then worked as a Miller Postdoctoral Fellow at the University of California, Berkeley before joining MIT as an Assistant Professor in July 2021. Prof. Choi’s research focuses on exploring dynamical phenomena that occur in strongly interacting quantum many-body systems far from equilibrium and designing their novel applications for quantum information science.

Department of Mathematics - Seminar on FinTech and Machine Learning - Problems and probable solutions of applying recent machine learning techniques to financial time series and data
Recent machine learning techniques such as deep learning and reinforcement learning were built on specific assumptions of the underlying data generation process. Financial time series frequently do not satisfy these assumptions. In this talk, we discuss the possible problems if these techniques are applied blindly. The solutions to these problems are in general problem specific. However, some of the pain can be alleviated by combining recent machine learning techniques with more classical statistical and econometrics insights. We will discuss these probable solutions with examples.
