A product state of a composite quantum system AB is customarily interpreted physically to mean subsystem A has property A1 and subsystem B has property B1. But this interpretation contradicts both the theory and observed outcomes of non-local interferometry experiments on the momentum-entangled state of two photons. These experiments demonstrate that product states must be interpreted physically as correlations, i.e. the product state means A has property A1 if and only if B has property B1. This clarification resolves the problem of definite outcomes and, with it, the measurement problem.

- An error occurs in Section 5. Post-measurement results in the RTO experiment are improperlystated to directly apply to the entangled measurement state itself. This puts the conclusions stated in the abstract into question
