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…

Review and suggested resolution of the problem of Schrodinger’s cat
Abstract This paper reviews and suggests a resolution of the problem of definite outcomes of measurement. This problem, also known as ‘Schrodinger’s cat’, has long posed an apparent paradox because

TLDR
A two-photon coincidence experiment with signal and idler photons produced in the process of parametric down-conversion is carried out and the coincidence rate exhibits a cosine variation with the optical path difference, with periodicity equal to the wavelength.
Experimental violation of Bell's inequality based on phase and momentum.
TLDR
Two-color photon pairs are selected by two double apertures placed to satisfy the phase-matching conditions at a down-conversion crystal and coincident two-photon detections are measured.
