What is quantum entanglement and what causes it?
There are no layman’s terms in quantum physics, because there are no intuitive counterparts that make sense. Quantum entanglement refers to what many originally believed was a paradox in quantum theory. The basis is a process of nuclear decay (or any process with similar results) where one nucleus ejects two particles in opposite directions with opposite properties (one spins clockwise, the other counterclockwise). According to quantum physics small particles behave differently after they have been “observed” by someone (or something) than they did right before they were observed. While this sounds weird, it happens to all small objects, and the technical term is “collapsing the wave function.” Since the two particles ejected by a nucleus must have opposite spin, if you observe one particle, you automatically know the spin of the other particle. According to quantum physics, once you measure one particle, it will behave differently that before. It also predicts the other particle will
