It leads to the Einstein-Podolsky-Rosen Paradox because it violates locality, allowing for information to travel faster than the speed of light. This idea is behind qubits, the basic unit of information in quantum computers. For 10 points, what phenomenon describes multiple particles which share linked quantum states
Output (English): Science
