I think you are. See below. You don't need to explain how to apply the collapse postulate. What you need to explain is why you even...

From what I can see, the literature is still not clear on this point--we have some references saying one thing, and some references...

An intermediate inferred mathematical description doesn't exist for photons 1 & 2 (or 3 & 4). Only the initial and final states. That...

What I say is remote in spacetime: The decision by Victor to swap (BSM) or not (SSM), which affects correlation seen by Alice and Bob...

In our ongoing example of a 4 photon entanglement swap (BSM on photons 2 & 3), per experiments like Kaltenbaek et al, it has been...

1. Still makes no sense in our context. There is no such thing as saying a system of unentangled particles (photons 2 & 3) being in a...

Not quite. The standard definition of an entangled state is a state that cannot be expressed as a product of states of subsystems. Huh...

1. Sorry, Zwiebach's writing notwithstanding, I reject this as a suitable reference. You must present something better. There should...

Again, I have provided multiple authoritative citations saying precisely the opposite. See Megidish figure 3 where indistinguishable vs...

Agreed, this is not a teleportation protocol. Because this is not teleportation, it is swapping. There are plenty of early swapping...

There is no such thing in any entanglement experiment anywhere, and no derivation as you claim other than what you make up. The Bell...
