The EPR argument, formulated by Einstein, Podolsky, and Rosen, assumes both that quantons (quantum particles) must have objectively real properties and that superluminal (faster than light) communication is impossible to conclude that quantum mechanics is incomplete. This argument is based on the idea that if quantum mechanics were complete, it would violate either the principle of locality (implying superluminal communication) or the principle of realism (the existence of objectively real properties independent of observation), leading to the conclusion that an additional, hidden variable theory is necessary.
