I have a question on the tension between special relativity and quantum mechanics, so please correct the category if this question is in the wrong location. I was looking at the write-up of an experiment: “Causality, relativity and quantum correlation experiments with moving reference frames” by H ZBINDEN, J BRENDEL, W TITTEL and N GISIN, Group of Applied Physics, University of Geneva, 1211 Geneva 4, Switzerland in 2001. http://www.ias.ac.in/pramana/fm2001/QT19.pdf The abstract summary is as follows: Abstract. Entanglement, one of the most important features of quantum mechanics, is at the core of the famous Einstein–Bohr philosophical debate  and is the principal resource for quantum information processing . We report on new experimental investigations of the properties of entangled photon pairs with emphasis on the tension between quantum mechanics and relativity [3,4]. Entangled photons are sent via an optical fiber network to two villages near Geneva, separated by more than 10 km where they are analyzed by interferometers . The photon pair source is set as precisely as possible in the center so that the two photons arrive at the detectors within a time interval of less than 5 ps (corresponding to a path length difference of less than 1 mm). This sets a lower bound on the ‘speed of quantum information’ to times the speed of light. Next, one detector is set in motion  so that both detectors, each in its own inertial reference frame, are first to do the measurement! The data always reproduces the quantum correlations. My question does not relate to the standard tensions between quantum mechanics and special relativity explored as a consequence of the EPR paradox, but rather relates to the question of temporal conflicts between SR and QM. According to Einstein, time is relative. In different frames of reference, time is measured at different rates and as a consequence there is no such thing as a universal present moment. The present moment is a human concept, significant psychologically only. However, if I am interpreting the data from the above experiment correctly, there would indeed appear to be a present moment. The present moment being defined as the moment of correlation between the entangled partners. If I did a thought experiment and had millions of entangled particles and placed them all over the universe in different temporal locations (i.e. gravity wells, fast spaceships etc) their moment of correlation would appear to be impervious to their relative time. It would seem to me that a universe that has relative moments and a universe that has a universal present moment are mutually exclusive conditions. I had a look in the SR section and the experimental test maintained by Tom Roberts at http://www.edu-observatory.org/physics-faq/Relativity/SR/experiments.html But I could find no mention of tests that test out relative time versus present time. Quantum entanglement experiments of particles in temporally separated frames of reference would suggest there is such a thing as a universal present moment. On the other hand Einstein’s concept of relative time emphatically rejects such a concept. Unlike the basic EPR paradox there does not appear anyway around this mutually exclusive/antagonistic set of conditions. This apparent temporal conflict between QM and SR appears to get no airplay. My question is what am I missing?
