摘要 (Abstract): 

Exploring the nucleon partonic structure has been remained as one of the main goals in particle and nuclear physics. The conventional methods in this topic are mainly focused on QCD global analysis and lattice QCD calculation. In this talk, we present an alternative technique, quantum computing, in calculating the unpolarized parton distribution function (PDF) and light-cone distribution amplitude (LCDA). We present a systematic quantum algorithm, which integrates both the hadronic state preparation and the evaluation of the real-time light-front correlations, to study the PDF and LCDA. As a proof-of-concept, we realize the first direct simulation of the PDF and LCDA in the 1+1 dimensional Nambu-Jona-Lasinio model. Our work suggests the encouraging prospects of calculating the nucleon partonic structure on current and near-term quantum devices.
