I was about to comment this very same thing.

When we talk about quantum teleportation, you should not think in terms of the star trek transporter at all - it is a completely different and unrelated concept.

In reality, if you want star trek style transporters, well - the star trek writers had to write in a mysterious magical "heisenberg compensator" device for a reason.

We can't scan a whole object at the atomic level and then reconstruct it perfectly because we can't know where all the atoms are AND their velocity.

Even if we could do it though, there's obvious issues with a device that "transports" people by killing them and creating a copy elsewhere.
