Are Entangled Photons the Same Particle?

[freerangequark]

Has it or can it be proven whether a "pair" of entangled photons are really the same photon (or not)?

Thanks,

A pair of entangled photons is 2 photons. They share a single wave function. There are a variety of ways to demonstrate this. Can you tell us why you would think that 2 photons are really 1?

It might be used as a basis of trying to understand their nature. Kinda like considering higher dimensions in an effort to unraveling other mysteries in physics.
