3. Bell Inequality Violation of Light Quarks in Back-to-Back Dihadron Pair Production at Lepton Colliders

Prof. Bin Yan (IHEP)

Spin correlations between particles produced at colliders provide valuable insights for quantum information studies. While traditional studies of quantum information at colliders are typically limited to massive particles with perturbative decay, we propose an innovative method to explore the Bell inequality in massless quark pair systems by analyzing the azimuthal correlations in back-to-back...

7. Parity and Environmental Effects on Quantum Entanglement and Bell Tests

Yong Du (IMP CAS)

Symmetries exhibit the beauty of nature, while their breaking reflects the reality of our Universe. In this talk, I will discuss how parity violation affects Bell tests by quantifying its impact on quantum entanglement and the violation of the Bell inequality, using spin-half bipartite systems as an illustration. On the other hand, spins interact with the environment, causing a decoupling...

15. Entanglement and beyond: Quantum information properties of on-shell scattering

Zhewei Yin (Northwestern University & Argonne National Lab)

Recently it has been noticed that many familiar quantum field theories (QFTs) may minimize or maximize the amount of entanglement in a scattering process. Studying the quantum information (QI) properties of final states for on-shell scattering will help establish whether fundamental physics can be formulated in terms of QI principles. We first present a universal relation between final state...
