 Einstein–Podolsky–Rosen paradox

The Einstein-Podolsky-Rosen (EPR) paradox is a thought experiment proposed by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935. It was intended to demonstrate what the authors considered the incompleteness of quantum mechanics. The paradox arises from the principles of quantum entanglement and raises questions about the nature of reality and the limits of quantum mechanics.
