  1. Einstein, Podolsky and Rosen’s argument of incompleteness of quantum mechanics

  2. Einstein, Podolsky and Rosen: Quantum mechanics is not complete According to EPR, any satisfactory physical theory must be: (1) Correct. (2) “Complete”.

  3. EPR’s “elements of reality” “If, without in any way disturbing a system, we can predict with certainty (i.e., with probability equal to unity) the value of a physical quantity, then there exists an element of physical reality corresponding to this physical quantity.”

  4. The EPR-Bohm experiment

  5. EPR’s argument • X2 and Y2 are both “elements of reality”. • In QM, X2 and Y2are incompatible observables (the knowledge of one precludes the knowledge of the other). QM is incomplete (according to EPR).
