- Are runs in an entanglement experiment independent or dependent?
If an entanglement experiment, whereby an entangled pair of particles is measured at both ends, is independent of the next entanglement experiment with another pair of entangled particles, how can there be a correlation? It seems that each independent run does not influence the next run, but wouldn't the correlation measured over several runs in that case not have to be zero? And if the correlation is significantly deviated from zero, does that not mean that the runs must be dependent? And what causes this dependence?
