Title: Attention to Quantum Complexity
Abstract:
With the exciting opportunities brought by quantum simulators, it is crucial to develop systematic methods to reliably and efficiently extract information from limited measurements of quantum state. We propose an attention-based neural network called quantum attention networks (QuAN), which is tailored for quantum state measurement data by respecting the permutation invariance of individual snapshots and attending to high-order correlations between different snapshots. The power of the QuAN is demonstrated through three examples:
(1) QuAN successfully learns entanglement transition from hard-core boson experiments, only using the Z-basis measurements. (2) QuAN learns the increasing complexity of deep random circuits from random circuit experiments. (3) QuAN saturates the error threshold in learning the topological state in the noise controlled simulated surface code data. The examples establish QuAN as a general-purpose machine for learning quantum complexity from limited mixed state data. I will discuss what the results imply for a versatile decoding scheme.
Bio:
Eun-Ah Kim is a professor of Physics at Cornell University. Her primary field of research is quantum condensed matter theory and aritificial intelligence for scientific research. Wielding AI tools, she is pushing the envelope of how much theoretical insight can be extracted from complex and big data and how quickly so-obtained theoretical understanding can feedback into experimental decisions. She received an Early Career Award from the National Science Foundation in 2010 and another Early Career Award from the Department of Energy in 2013. She was named a Fellow of the American Physical Society in 2020. She was selected a Radcliffe fellow during 2022-2023 and she received a Simons Fellowship the same year. She obtained her Ph.D. at the University of Illinois at Urbana-Champaign in 2005 and then held a postdoctoral fellowship at the Stanford Institute for Theoretical Physics. She then started as an assistant professor at Cornell University in 2008, where she stayed since.
