High energy hadronic scatterings are essential tools to probe the fundamental partonic (quark and gluon) structure of nucleon/nucleus and are the only method in laboratory to test Quantum Chromodynamics (QCD), the strongest force in nature. However, due to the non-perturbative property of QCD in hadronic scale and the real time dynamics in high energy scatterings, it is extremely challenge to fully compute these processes either in perturbative QCD or via lattice QCD. Inspired by the great promise of quantum computers using their natural capability of simulating real-time evolutions, there has been a rapidly growing wave of interest in implementing quantum computing methodologies to particle and nuclear physics in recent years. In this talk, I will discuss recent progresses in using quantum computing to explore hadronic scatterings, including the direct calculation of initial state parton distribution functions in hadron, the intermediate state partonic scatterings, as well as the final state hadronization process. 



Hongxi Xing is a nuclear theorist and Professor of Physics at the South China Normal University (SCNU). He obtained Ph.D. in 2012 from Central China Normal University, jointly trained by Lawrence Berkeley National Laboratory. He held postdoctoral positions at University of Science and Technology of China, Los Alamos National Laboratory and Argonne National Laboratory/Northwestern University before joining the Institute of Quantum Matter of SCNU as a full professor in 2018. He was a recipient of the NSFC Excellent Youth Scholar. His research interest focuses on hard probes in heavy ion physics, nucleon structure, as well as the application of quantum computing in high energy physics.
