Definition ∞ Quantum nonlocality describes the phenomenon where entangled particles exhibit instantaneous, correlated behavior regardless of spatial separation. This property indicates that measurements performed on one particle in an entangled pair immediately influence the state of its distant partner, without any classical information exchange. It represents a fundamental departure from classical physics, suggesting a deeper, interconnected reality at the quantum level. The existence of quantum nonlocality has been experimentally verified through Bell tests.
Context ∞ Quantum nonlocality is a foundational concept in quantum information science, underpinning the security of quantum cryptography and the operational principles of quantum computing. In digital asset security, understanding nonlocality is critical for developing future quantum-resistant cryptographic algorithms and secure communication protocols. Research continues to explore its implications for distributed systems and verifiable randomness generation.
