Violation of Bell Inequality with unentangled photons

I agree that you can't just bin things into binary measurements. I'm not sure exact continuity is required. For example, with a momentum...

No. Interference between position and momentum eigenkets? What does that mean? I don't understand. To me the key point is whether or...

How does it even make sense to combine position and momentum eigenkets? I don't understand what you're doing here.

I see, basically you're constructing a state in which two particles are known to be at the exact same position, but we don't know what...

Even in "short form", your state was not entangled. It was a product state. That's obvious from what you wrote. Assume the particles...

You need to prepare an entangled state, as @gentzen has pointed out. For example, a momentum entangled state could be (ignoring...

Not if they're built in space. Which is the obvious next step, just as it was with optical telescopes.
