Non-separability refers to the concept that two particles can be entangled and behave as a single system, even when separated by large distances. Non-locality, on the other hand, refers to the idea that the behavior or state of one particle can affect the behavior of another particle instantaneously, regardless of the distance between them.
Non-separability and non-locality are closely related concepts in quantum physics. Non-separability is a necessary condition for non-locality to occur, as particles must be entangled in order for their behavior to be correlated regardless of distance.
No, non-locality is a phenomenon that is unique to quantum mechanics and cannot be explained by classical physics. In classical physics, the behavior of particles is determined by their location and physical properties, whereas in quantum mechanics, particles can be entangled and behave non-locally.
Non-locality violates the principle of causality, which states that an effect must always be preceded by its cause. In non-locality, the behavior of particles can be correlated instantaneously, regardless of the distance between them, which goes against the idea of cause and effect.
Understanding non-separability and non-locality has led to significant advancements in technologies such as quantum computing and quantum cryptography. It has also helped to deepen our understanding of the fundamental principles of quantum mechanics and the nature of reality at the smallest scales.
