報(bào)告摘要：
The scattering amplitudes program aims to obtain observables from quantum field theory without cumbersome local formulations such as Feynman diagrams. A key step in this procedure is to determine the constraints satisfied by the on-shell amplitudes, according to the guiding principles of the theory in consideration. Recently a novel group of constraints originated from concepts in quantum information science has been increasingly drawing people's attention. I will first discuss the investigation on the amount of entanglement resulted in particle scattering, and reveal a universal correspondence between entanglement entropy and (semi)-inclusive cross sections. A careful formulation of wave packets for the initial states is essential in arriving at this relation. I will then discuss in the context of particle scattering the notion of magic, which quantifies the computational advantage of quantum states over classical algorithms. Research on this topic is still in its early stage, and can benefit both fundamental physics and quantum information science.
