Abstract: 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.
