key to the RQM analysis is to remember that the results obtained on each "wing" of the experiment only become determinate for a given observer once that observer has interacted with the other observer involved. As far as Alice is concerned, the specific results obtained on Bob's wing of the experiment are indeterminate for her, although she will know that Bob has a definite result. In order to find out what result Bob has, she has to interact with him at some time in their future light cones, through ordinary classical information channels. The question then becomes one of whether the expected correlations in results will appear: will the two particles behave in accordance with the laws of quantum mechanics? Let us denote by the idea that the observer (Alice) measures the state of the system (Alice's particle). So, at time , Alice knows the value of : the spin of her particle, relative to herself. But, since the particles are in a singlet state, she knows that and so if she measures her particle's spin to be , she can predict that Bob's particle () will have spin . All this follows from standard quantum mechanics, and there is no "spooky action at a distance" yet. From the "coherence-operator" discussed above, Alice also knows that if at she measures Bob's particle and then measures Bob (that is asks him what result he got) or vice versa the results will be consistent: Finally, if a third observer (Charles, say) comes along and measures Alice, Bob, and their respective particles, he will find that everyone still agrees, because his own "coherence-operator" demands that and while knowledge that the particles were in a singlet state tells him that Thus the relational interpretation, by shedding the notion of an "absolute state" of the system, allows for an analysis of the EPR paradox which neither violates traditional locality constraints, nor implies superluminal information transfer, since we can assume that all observers are moving at comfortable sub-light velocities. And, most importantly, the results of every observer are in full accordance with those expected by conventional quantum mechanics. Whether or not this account of locality is successful has been a matter of debate. Derivation A promising feature of this interpretation is that RQM offers the possibility of being derived from a small number of axioms, or postulates based on experimental observations.
