DESCRIPTION:Speakers: Yu-Chen Guo（郭禹辰） (Liaoning Normal Universi
 ty)\n\nAbstract: The intersection of high energy physics and quantum info
 rmation science has opened new avenues for exploring fundamental physics a
 t high energy colliders. Future lepton colliders\, characterized by their
  clean collision environments and precise beam controls\, provide an ideal
  experimental platform for high energy quantum information measurement. In
  this talk\, we present a comprehensive study of quantum information obser
 vables in fermion pair production—specifically top pair production\, muo
 n pair production\, and Bhabha scattering—which represent the mass thres
 hold behavior\, the Z-pole resonance\, and the s/t-channel interplay. We w
 ill explore how longitudinal beam polarization can serve as a controllable
  quantum channel to manipulate the two-qubit spin density matrix. Our disc
 ussion focuses on three key quantum resources: quantum entanglement\, Bell
  nonlocality\, and magic. Our findings highlight that beam polarization is
  not merely a tool for enhancing statistical precision\, but a fundamental
  knob for probing and controlling quantum resources at the high energy fro
 ntier.Biography:Yu-Chen Guo is an Associate Professor of Physics at Liaoni
 ng Normal University. He earned his Ph.D. from Liaoning Normal University 
 in 2017 and recently completed a visiting scholar appointment at the Unive
 rsity of Pittsburgh's PITT PACC (2025-2026). His primary research focuses 
 on new physics beyond the Standard Model\, and he has published over 30 pa
 pers in journals such as JHEP and PRD. His recent research interests are c
 entered on quantum information measurements at high-energy colliders.Alter
