It's unlike a classical system, in which the particles are distinguishable, and "particle A" on one side of a room is a distinct entity from "particle B" on the other side of the room. If two particles are truly quantum entangled, there is no "particle A" and no "particle B" because there is no way to know which is which: There is just a two particle system with the interchangeable entities separated in space(-time.)
Given that, a quantum system constructed remotely from its information (state vector or wave function) is NOT a copy. It is the original system.
Frank Tipler has an interesting religious and metaphysical discussion of this in his book The Physics of Immortality in which he discusses the fact that physical resurrection is a real possibility, because all God needs to know is your state vector in order to construct you. Since every electron in the universe is the same as every other [and indeed every quantum particle in the universe is the same as any other] it would still be the same "you" no matter what materials he used -- or where he chose to reassemble them; and it would be you... NOT a clone or identical twin.
Looking at it another way, I think every individual electron exists on it's own, just as humans and planets exist on their own.
From Edward Frenkel, we have "... there are two kinds of elementary particles; fermions and bosons. The former are the building blocks of matter (electrons, quarks, etc), and the latter are the particles that carry forces (such as photons). The elusive Higgs particle, discovered recently at the Large Hadron Collider under Geneva, is also a bison."
Sorry, but the reason I gave the definition for teleport is that the word does not mean replicate, observe, etc. It means to transport (a body).
The “teleportation” they are talking about here is not the deconstruction of a body and reconstruction of another. It is an observation on the entanglement of data associated with two separate bodies. I see nothing in the article to disabuse the notion that this was a replication (or observation of entanglement, if you prefer), rather than the actual deconstruction/reconstruction of the original body.
Words mean things - and I do not think that word means what they think it means.
