Does the quantum collapse make sense? Quantum Mechanics vs Multisimultaneity in interferometer-series experiments

It is argued that the three assumptions of quantum collapse, one photon-one count, and relativity of simultaneity cannot hold together: Nonlocal correlations can depend on the referential frames of the beam-splitters but not of the detectors. New experiments using interferometers in series are proposed which make it possible to test Quantum Mechanics vs Multisimultaneity.Comment: 18 pages Latex, 2 eps figures.

Deriving Bell's nonlocality from nonlocality at detection

It is argued that Bell's nonlocality is a particular case of nonlocality at detection, which appears already in single-particle interference experiments. The unity of nonlocality and local causality is crucial to provide a consistent description of the world.Comment: 9 pages, 2 figure
