Nonlocality is a concept in physics that refers to the idea that objects can be connected in such a way that their properties are correlated instantaneously, regardless of the distance between them. This phenomenon challenges the principles of classical physics, which assume that causality is strictly localized and that information cannot travel faster than the speed of light. Nonlocality is commonly studied in the context of quantum mechanics, where particles can exhibit entanglement, a form of nonlocal correlation where the state of one particle is dependent on the state of another, even if they are separated by large distances. Understanding nonlocality has implications for the foundations of quantum mechanics, as well as for potential applications in quantum information processing and communication.
