“it’s not teleportation!! The information/signal still needs to travel through the cables…Traveling through something is the opposite of teleportation.”

No, it isn’t. Teleportation is when you conduct a destructive scan on an object, transmit that information through a medium, and then reassemble it at the other end using different parts. The teleported object is made of a different set of atoms but with the same informational content, so it is indistinguishable from the original, and the original ceases to exist.

Ever heard “Beam me up, Scotty!” Quantum teleportation is literally teleportation. You just don’t seem to know what teleportation is and are for some reason comparing it to magic.

It is literally teleportation. The original particle is “scanned” and its quantum state “destroyed,” that “scanned” information is transmitted down a wire or could even be transmitted with a laser beam if we want to name our particle Scotty, and then the recipient of that information uses it to reconstruct the quantum state on a different particle.

The reason quantum teleportation is interesting is because the no-cloning theorem disallows you from copying an unknown quantum state of one particle into another, unless the original quantum state is scrambled / “destroyed” in the process. Hence, you cannot clone it, but you can teleport it. It’s pretty basic in computers to be able to copy memory from one register to another, but that’s forbidden by the laws of quantum mechanics, but you can at least teleport data between registers.
