Coexistence of CHSH Nonlocality and KCBS Contextuality in a Single Quantum State
Khai Nguyen, Duc M. Doan, Hung Q. Nguyen
Contextuality and nonlocality are distinct manifestations at the foundation of quantum mechanics, yet their coexistence within a single quantum state remains subtle. In a hybrid CH…

Hardy nonlocality for entangled pairs in a four-particle system
Duc Manh Doan, Hung Q. Nguyen
Nonlocality can be studied through different approaches, such as Bell's inequalities, and it can be found in numerous quantum states, including GHZ states or graph states. Hardy's…
