The nonlocality of quantum correlations is a fundamental feature of quantum theory. The benchmark for distinguishing quantum theory from local hidden variable theories (LHVT) is the testing of Bell's inequalities. Recent advances in photon entanglement experiments have made significant progress, addressing potential loopholes and observing significant violations of Bell's inequalities....

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...

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

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...
