Interplay of Quantum Resources in Nonlocality Tests

Nonlocality, evidenced by the violation of Bell inequalities, not only signifies entanglement but also highlights measurement incompatibility in quantum systems. Utilizing the generalized Clauser-Horne-Shimony-Holt (CHSH) Bell inequality, our high-efficiency optical setup achieves a loophole-free violation of 2.0132. This result provides a device-independent lower bound on entanglement, quantified as the entanglement... Show more
