Description
Quantum nonlocality, a fundamental feature of quantum mechanics, is frequently associated with the experimental violation of Bell-Clauser-Horne (Bell-CH) inequalities. We present a set of novel methods for the rearrangement and linear inequalities to derive a broad class of Bell-CH inequalities, which can be violated by particular quantum-entangled states. The rapid advancements in Quantum Information Science (QIS) have opened new avenues for probing fundamental aspects of physics. Central to distinguishing quantum information from classical information, quantum nonlocality has been extensively investigated through the violation of Bell-CH inequalities in particle decay processes. Nonetheless, a comprehensive framework grounded in quantum information theory for particle interactions remains elusive. To bridge this gap, we propose a generalized quantum measurement framework for spin-1/2 hyperon decay processes, aligning this approach with established theoretical models and applying it to the joint decay of correlated $\Lambda \overline{\Lambda}$ pairs. Utilizing quantum simulations, we demonstrate the violation of Bell-CH inequalities in hyperon decays. This generalized measurement framework is versatile and can be extended to a range of high-energy processes, including the decays of vector mesons, $J/\psi$ and $\psi(2S) \rightarrow \Lambda \overline{\Lambda}$, within the Beijing Spectrometer III (BESIII) experiment at the Beijing Electron Positron Collider (BEPC).
