Bell Test Violation

Definition ∞ A Bell Test Violation confirms the existence of quantum nonlocality, a property where particles remain connected regardless of distance. This experimental outcome indicates that certain quantum systems exhibit correlations stronger than classical physics allows, disproving local realism. It provides empirical evidence that measurements on entangled particles are instantaneously correlated, irrespective of spatial separation. Such violations are foundational to quantum information science.
Context ∞ In the realm of quantum computing and cryptography, Bell Test Violations are crucial for verifying the integrity of quantum systems used in generating truly random numbers or establishing secure communication channels. Current research focuses on improving the robustness and scale of these tests to validate advanced quantum technologies, particularly for applications relevant to post-quantum security.
