What I was thinking of was the Quantum eraser experiment, when I spoke of the experimenter as part of the entanglement DRc. As for "The reality of one is dependent on the nature of a measurement of the other, and vice versa, in accordance with the predictions of QM - and completely in opposition to LR (local realism)"
I don't know what 'local realism' should be seen as? Even macroscopically, in relativity, you have Lorentz contractions. If you define them as real, which I do, then there is no such thing as a 'defined distance' globally, Lorentz transformations non-withstanding, I differ between 'conceptual comparisons', and what you see locally. I also define it such as 'what you see is what you got', meaning that if you're 'speeding away' like a muon the Lorentz contraction I expect you to see will be as 'real' as it can be in this 'reality', for you.
If you mean that I state that we can know the spin before measuring? Or that I think that "all objects must objectively have a pre-existing value for any possible measurement before the measurement is made." then I sincerely doubt that one.
I expect the observer to define his reality through his local observations, and as he compares that to other frames of reference, then use his local definitions. Just as any experimenter does, using his own 'clock' defining a time for example. But I don't expect a entanglement to be known before the measurement?
Also I expect a outcome to be defined by the relations circumstancing it, including the experimenter, and his choice of measuring, set-up etc.
As I understand it Aspect proved that there was no such thing, as pre-existing values? That doesn't mean that I'm wrong in defining it from locality. And it doesn't mean that I necessarily must be wrong in saying that that the experimenter defines the experiment, as in the
delayed choice quantum eraser.
In it they say "Some have interpreted this result to mean that the delayed choice to observe or not observe the path of the idler photon will change the outcome of an event in the past. However, an interference pattern may only be observed after the idlers have been detected (i.e., at D1 or D2)." as the signal photon reach D0 before the idler, due to a shorter 'path'.
But it will still be the experimenters choice that defines what there is to see, "the choice of whether to preserve or erase the which-path information of the idler need not be made until after the position of the signal photon has already been measured by D0."
And it is a still a function of both photons in the entanglement, meaning that your choice defines the outcome for the whole entanglement.
