The EPR Argument in a Relational Interpretation of Quantum Mechanics

It is shown that in the Rovelli relational interpretation of quantum mechanics, in which the notion of absolute or observer independent state is rejected, the conclusion of the ordinary EPR argument turns out to be frame-dependent, provided the conditions of the original argument are suitably adapted to the new interpretation. The consequences of this result for the ‘peaceful coexistence’ of quantum mechanics and special relativity are briefly discussed.
