Quantum entanglement
A quantum entanglement occurs when pairs or groups of particles are generated or interact in ways such that the state of each particle cannot be described independently of the others.
Explanation
A quantum state must be described for the system as a whole, even when the particles are separated by a large distance.
HistoryChinese-American physicist Chien-Shiung Wu was the first to demonstrate quantum entanglement in 1949. |
