Quantum teleportation over 143 kilometres using active feed-forward

Here is what I take to be an acceptable definition of teleporatation, which comes from Wikipedia:

Teleportation is the transfer of matter from one point to another without traversing the physical space between them

So under this definition, would you agree that quantum teleportation is not "regular" teleportation, since although information is traversing space without moving "through" it, matter is not?

I'm not really arguing semantics anymore, I'm just unclear whether the latter part of that question ("since...") is factually true, since I don't understand quantum stuff.

I think term teleportation is still valid because they can entangle and teleport any kind of particles. Photons are merely used because of their convenience.

You can entagled protons, electorns. Hell, I think they managed to demonstrate entanglement on a larger scale.

It seems to me like no particles are being teleported, becuse no matter is being moved. It's just information (i.e, the state of a particle) that is being duplicated in the same kind of particle on the other end.
