The number one problem with quantum teleportation is the name. It should have been named quantum telegraphy. There would be fewer cranks.

The original paper [1], written by some of the best scientists of the era, correctly called it "Teleporting an Unknown Quantum State", and nowhere did it use the term "quantum teleportation". Later, in interest of conciseness, the ambiguous term "quantum teleportation" got introduced. It would have been better if "quantum state teleportation" had been used.

but quantum state is all that can ever be measured about the system so seems a redundant word

No mass is teleported, that's the key. A state of one mass is copied to another mass, but no mass is moved in the sense that would invoke General Relativity, as far as I understand.

I suppose teleporting a state in such a way that the target mass would change its motion in a significant way ("accelerated") without affecting the source mass is impossible, because it would break the conservation of impulse.

Names have the power to guide perception about what they identify.

"Quantum teleportation" is as easily misused as that of "dark matter".

Is it actually matter? If the answer isn't a definite yes then the term doesn't help long term but maybe it's good enough for now. "Dark energy" is another term. Is it accurate? Maybe. It alse works for plenty of people for now.

Both terms assist as long as they help discussion but the lay person easily gets confused and experts can get mislead as well. If you think of it as matter then you design experiments in particular ways. You think about it in those terms. You don't think of it in other ways to the same extent.

Quote from Wikipedia: https://en.m.wikipedia.org/wiki/Dark_matter

"The primary evidence for dark matter is that calculations show that many galaxies would fly apart instead of rotating". Not exactly a ringing endorsement of matter as real. But as long as it helps the overall investigation then it's ok for now. Calculations can accurately describe reality and guide decisions so why not.

"Quantum teleportation" as a term is easily derailed no matter how helpful it describes a portion of reality. Maybe it simply needs a few more words nearby to put the brakes on people's imagination.

The map of the place is not the place.

or even something more descriptive like quantum state disambiguation.

How is that more descriptive?

The most natural name would be "replication" (of the quantum state), but given than the original is lost and only the replica survives "teleportation" doesn't look so bad.

"quantum state transfer"?
