Quantum entanglement is a phenomenon where two or more particles can be connected in such a way that the state of one particle is instantly correlated with the state of the other, even if separated by a large distance. Bell's theorem is a result in quantum physics that shows the mathematical incompatibility between the predictions of quantum mechanics and the idea that physical properties have pre-existing values (known as "local realism"). The theorem was demonstrated experimentally, and the results showed that quantum entanglement can indeed lead to statistical correlations that cannot be explained by local realism.   In simple terms, quantum entanglement and Bell's theorem show that particles can be connected in a mysterious way, such that the state of one particle is ...
