Quantum simulation of HEP has seen remarkable growth in recent years. Nevertheless, there is a continuous need for advancements in the overall simulation framework. I will discuss a specific foundational element - digitization, a crucial method for encoding field variables into qubits. This is particularly relevant for gauge theories with local symmetry and field variables of infinite dimension. During the talk, I will explore the connection between gauge theory digitization methods and approximate error correction codes, and present the existence of error thresholds below which gauge-redundant digitizations combined with error correction have better fidelity than the gauge-fixed digitization.



Yingying Li obtained her Ph.D. from the Hong Kong University of Science and Technology in 2019. From 2019 to 2022, she was a research associate (postdoc) at Fermi National Accelerator Laboratory in the United States. In 2023, she joined the University of Science and Technology of China as an assistant professor. Her research focuses on precise testing of the Standard Model and new physics, including quantum simulations of lattice QCD and collider phenomenology.
