A key step in this procedure is to determine the constra ints satisfied by the on-shell amplitudes\, according to the guiding princ iples of the theory in consideration. Recently a novel group of constraint s originated from concepts in quantum information science has been increas ingly drawing people's attention. I will first discuss the investigation o n the amount of entanglement resulted in particle scattering\, and reveal a universal correspondence between entanglement entropy and (semi)-inclusi ve cross sections. A careful formulation of wave packets for the initial s tates is essential in arriving at this relation. I will then discuss in th e context of particle scattering the notion of magic\, which quantifies th e computational advantage of quantum states over classical algorithms. Res earch on this topic is still in its early stage\, and can benefit both fun damental physics and quantum information science.\n\nBio:\nDr Zhewei Yin o btained his BSc degree in 2015 at Peking University\, China\, and his PhD degree in 2020 at Northwestern University\, USA. He then became a postdoct oral researcher at Uppsala University\, Sweden\, after which he has been h olding a joint appointment as a postdoctoral fellow at Northwestern Univer sity and Argonne National Laboratory\, USA. He works in the field of theor etical high energy physics\, with a focus on discovering new properties an d developing modern methods in scattering amplitudes and effective field t heories\, as well as connecting these formal development to particle pheno menology\, gravitational wave physics and quantum information science.\n 殷喆伟博士于2011至2015年就读于北京大学，获得物理学学 士学位；2015年至2020年就读于美国西北大学（Northwestern Un iversity），获得理论物理学博士学位；2020年至2023年就职 于瑞典乌普萨拉大学（Uppsala Universitet）理论物理系，目 前是美国西北大学和阿贡国家实验室（Argonne National Labora tory）联合博士后研究员。研究方向为高能理论物理，包 括有效场论、散射振幅等方面的新性质、新方法的探索 ，以及这些新成果在粒子物理唯象学、引力波唯象学和 量子信息领域等方面的应用。\nhttps://indico.ihep.ac.cn/event/2 5361/ LOCATION:B105 (CHEP) URL:https://indico.ihep.ac.cn/event/25361/ END:VEVENT END:VCALENDAR
