Yes, I see. And there are strange effects, like "unidirectional quantum steering". http://arxiv.org/abs/1511.01679http://arxiv.org/abs/1511.01231 Difficult (for me) to understand this a-symmetric non-locality in terms of MWI. s.

Rather the idea is that "splitting" into worlds is local, not global; so one experimenter locally splits into copies that see |+> and |-> when they measure their particle, likewise the other experimenter splits into copies that saw |+'> and |-'>. But until their future light cones overlap there are no "worlds" containing facts about what *both* experimenters saw. ----- In a Franson interferometer, two (time-energy entangled photons) travel in opposite directions from an EPR source. Each photon then enters an *imbalanced* Mach-Zehnder interferometer (such that there is no single-photon interference in each Mach-Zehnder interferometer). Detectors measure the outputs of the two identical imbalanced Mach-Zehnder interferometers and the coincidences between the detectors are recorded, showing there is a *two-photon* interference, that is to say the two entangled potons follow the *same* path in each (space-like separated) interferometer. A sign of non-locality (non-separability) in the "usual" interpretation. I'm trying to figure out how all that works in a *local* MWI ...... -- You received this message because you are subscribed to the Google Groups "Everything List" group.
