Definition of quantum entanglement

: a property of a set of subatomic particles whereby a quantum characteristic (such as spin or momentum) of one particle is directly and immediately correlated with the equivalent characteristic of the others regardless of separation in space In quantum entanglement, subatomic particles maintain a relationship—for instance, vibrating when the other vibrates—even when separated and even if they are at great distances from each other.— Sean Hamill Quantum entanglement occurs when two systems share a common quantum mechanical state. Such systems also share a common fate, even if they become physically quite separated. The results of a measurement performed on one will determine the results of future measurements on the second.— Claudia Tesche

First Known Use of quantum entanglement
