‘Relational Einstein’ - revisiting the relational EPR — •Matthias Martin Ackermann — University of Bristol, United Kingdom

Relational EPR (R-EPR) was initially proposed to dissolve the commonly assumed non-local implications of the original EPR-argument and claimed to restore locality in Quantum Mechanics (QM). In this paper I suggest two things: first of all, an exchange of the foundation of R-EPR’s analysis; meaning that I refer to Einstein’s own incompleteness argument instead of EPR. The main reason behind this replacement is R-EPR’s explicit reference to ‘Einstein’s realism’ while at the same moment developing the relational approach from the EPR. And secondly, based on the first step, I consider a reading of Relational EPR’s analysis as separable and local in the framework of Einstein’s argument. However, widening the scope of the framework can turn R-EPR’s core strength - the de-objectivisation of reality in terms of observer-relativity - into a major drawback. All in all, in its current state, Relational Quantum Mechanics is unable to provide an unambiguous account of locality.
