Quantum Nonlocality

Quantum nonlocality refers to the phenomenon where particles become interconnected in ways that classical physics cannot explain, even when separated by large distances. In quantum mechanics, measuring one particle can instantaneously influence the state of another, regardless of the space between them. This challenges our traditional notions of locality, where objects are only affected by their immediate surroundings. Nonlocality plays a crucial role in quantum information theory, enabling technologies like quantum computing and quantum cryptography, where secure communication relies on these unique connections between distant particles.
