Quantum simulation in High Energy Physics (HEP) has advanced significantly in recent years. Nevertheless, further development of a comprehensive simulation framework remains an important challenge. In this talk, I will first highlight the essential role of quantum computing in HEP and review recent progress in the field. I will then discuss the impact of gauge redundancies on quantum simulations of quantum field theories, with particular emphasis on digitization—the encoding of field variables into qubits. Finally, I will present quantum algorithms for the efficient preparation of initial states in quantum field theory simulations.

Biography

Ying-Ying Li is an Associate Professor at the Institute of High Energy Physics (IHEP) and a Simons Emmy Noether Fellow at the Perimeter Institute for Theoretical Physics in Canada. She received her Ph.D. from HKUST in 2019, followed by postdoctoral research at Fermilab (2019–2022) and an Assistant Professorship at USTC (2022-2024). Dr. Li is the principal investigator of several research projects, including the NSFC Young Scientists Fund (Categories B and C) and a National Key R&D Program Young Scientist Project. Her research focuses on developing first-principles quantum computing frameworks for particle physics, aiming to provide new tools for studying non-perturbative dynamical processes at colliders.
