What scientists mean by "teleportation" is more like this: you have one particle A here, one particle B there, and by "teleportation" you make particle B have the same state as particle A.

Critical point: for each particle you want to "teleport", you have recipient particle standing by to receive it.

Well, you move the state of A onto B. By the no-cloning theorem A can no longer have the same state once B has it. Hence the term "teleportation."

What happens to the first particle once its state has been transferred? Is it a swap? Or does it go to some other unique state C?

[TheRealPomax]

The particle ends up either getting destroyed during the measurement (e.g. that free photon or electron will no longer be), or its quantum state will have been collapsed into something that can no longer be used in a quantum algorithm.

[Symmetry]

It'll have some new unique state.
