SUMMARY

The discussion centers on the theoretical limits of teleporting objects, particularly focusing on the size constraints imposed by quantum mechanics. Participants argue that teleportation may be feasible for specially prepared objects, but a general device for teleporting any object does not exist. Key points include the destructive nature of teleportation, the challenges of scanning larger objects, and the implications of decoherence effects. The consensus leans towards the idea that size alone is not the primary barrier to teleportation, but rather the scalability of the teleportation protocol itself.

A electron has a "spin" state. But the spin state is not the electron.

The quantum teleportation experiments that have been done only teleported the quantum state of the entangled ensemble. It does not teleport the object itself.

Zz.

i agree.

What is actually teleported?
A. Peres
...There are no "unknown quantum states." The phrase is self-contradictory. Moreover, Alice and Bob are only inanimate objects: They know nothing. What is teleported instantaneously from one system (Alice) to another system (Bob) is the applicability of the preparer's knowledge of the state of a particular qubit in the systems...

...07 December 1998, and to the other teleporters, “Swedish Bikini Team”
The Swedish television crew came and went yesterday with little incident. No questions at all
about the soul this time: I was spared (and maybe so were you). But I didn’t pass up the chance to try to get an unsuspecting audience to think deeply about the wave function. (This audience, in fact, really will be unsuspecting: the footage was for a Swedish children’s show.)
The question came, “What material is teleported? What is it that is transported instantaneously
from Alice to Bob?”
I said, “The only thing that is teleported in quantum teleportation is what the preparer HAS
THE RIGHT TO SAY about Bob’s system. It is his description, his predictions, that jump instantaneously from one system to the other.”
A blank stare, “But what MATERIAL is teleported?”
“That is the material.”
He seemed pleased and left it at that. When he left, I had a look at my atlas to refresh the old
memory: Sweden was indeed not so very far from Copenhagen...
