时 间：2022年9月13日（星期二）上午 10:00
High energy physics is facing challenges of e.g., understanding the origin of observed baryon asymmetry, the nature of dark matter. Scenarios to address these challenges often involve dynamics that at present cannot be solved due to computational or theoretical limitations. An elegant solution exist in the form of real-time simulation, though hampered by limited quantum resources for the foreseeable future. In my talk, I will motivate the critical need for real-time simulation in high energy physics, discuss existing challenges and techniques involved. Then I will focus on improved Hamiltonians to lower the qubit requirements. With derivations of the matrix elements for the improved terms and constructions of the corresponding quantum circuits, we pave the way of simulating these improved Hamiltonians in real-time for general gauge theories.
