The EPR Argument and Quantum Nonlocality

We view the final remark of the EPR paper : "one would not be able to arrive at the above conclusion if two or more physical quantities are regarded as simultaneous elements of reality only when they can be simultaneously measured or predicted". On this point of view, because of the collapse of the wave function of the combined system, the EPR entangled relations (or correlations) of momenta and positions belonging to two spatially separated particles considered in the first part of the paper do not hold good simultaneously for two separate measurements. This case does not reconcile with the locality principle and hence exhibits quantum nonlocality. Moreover, it is quite compatible with uncertainty principle. It is concluded that the EPR argument does not exhibit any paradox.
