- Abstract summary: A coherence interpretation is conducted for the nonlocal realism of the space-like separated photons observed in Phys. Rev. Lett. 84, 1 (2000).
A fixed sum-phase relation between entangled photons is a prerequisite, which cannot be explained by conventional particle nature-based quantum mechanics.

- Abstract: The delayed-choice thought experiment proposed by Wheeler has been
demonstrated over the last several decades for the wave-particle duality of a
single photon. The delayed-choice quantum eraser proposed by Scully and Druhl
has also been intensively studied for the violation of the cause-effect
relation of a single photon as well as a pair of entangled photons in an
interferometric system. Here, a coherence interpretation is conducted for the
nonlocal realism of the space-like separated photons observed in Phys. Rev.
Lett. 84, 1 (2000). As a result, coherence solutions of the observed nonlocal
fringes are deterministically derived from coincidence detection-caused
selective measurements, where the resulting product-basis superposition becomes
the origin of the otherwise quantum mystery of the nonlocal fringes. For this,
a fixed sum-phase relation between entangled photons is a prerequisite, which
cannot be explained by conventional particle nature-based quantum mechanics.

This paper examines the arguments that relate the photon momenta to the "which path" question at the heart of quantum mechanics.
We show that the linear momenta imparted to apertures or mirrors, or the angular momenta picked up by strategically placed wave-plates, could lead to an identification of the photon's path only at the expense of destroying the corresponding interference effects.
