Feynman rules for Entangled photons

[Vanadium 50]

There is not such thing as Feynman rules.

What? Of course there are. And if you don't think there are, why did you put them in the thread title?

Yes, there are. They just don't mean what your thread title implies that they mean, as @Demystifier pointed out in post #26.

If you think it is B level

We don't. That's the point. We think the questions you are asking are A level, but your level of knowledge is not. Your level of knowledge appears to be B level, and there is no useful answer we can give you at B level. The only useful feedback we can give you at B level is to increase your level of knowledge. Study textbooks that deal with path integrals for multiple-particle systems. Then you will be able to frame questions that we can usefully answer.

Thread closed.
