Of course the most disturbing part is the question of what happens from your point of view when you get transported. You'd think that from your POV, you die instantly as you are torn apart on a atomic level and that the person that is reconstituted on the other end only think they are you because they have all of your memories. There'd just be no way to know what happens from a person's perspective.

liam76: About time they got cracking on that ansible thing.


If I recall correctly, quantum teleportation is still limited by c.

The problem with the ansible is that (if I'm remembering my quantum right: It's been 2 years since graduate quantum), when you entangle to particles-measuring one causes the *wave function* of the other to collapse: but you cannot control *how* it does so. (That is, I can measure an entangled particle and go "aha! This one has momentum X.. sot he other must have momentum -X, and its wave function has now collapsed! But I cannot go "I will ADD momentum X to my particle, causing the other to have momentum -X!")

Now, you might go "Wait! But if we can choose to collapse some wave functions, but not others, we could still use that as the basis for sending ones and zeroes!"
But, again, that doesn't quite work: because (again, I'm pretty sure I'm remembering this right), you cannot measure to see if the waveform has collapsed yet. . I *think*. I definately recall a lecture explaining why the ansible couldn't work, but I admit I may be getting the details a bit wrong. =/.

It's not so much about communicating data, it's about _securely_ communicating data. Collapsing the wave function at your end gives a corresponding pattern of states at the other end, meaning that both you and the recipient now have matching encryption keys without sending said keys through some delivery system where they can be hijacked by a man in the middle and your message read.

Current encryption protocols are limited by the fact that, well, you have to either have already given the key to the recipient in the past (so it never changes, meaning if it's stolen once you're compromised forever) or you have to transmit it to them before (or I guess after) sending the message, where it can be intercepted. You just have to time it so that the receiving computer reads the states within a relaxation interval of the sending computer. Which can be a pretty short time, but iirc some relaxation periods can be extended artificially by various engineering workarounds.

Star Trek didn't invent teleportertation as a way to "wow" us with future as much as a cost-cutting and screentime-saving measure.

Bringing shuttlecraft prop to a set, or worse yet on-site, is expensive and logistically troublesome.

In film, this is the "establishing shot" to tell the audience "OK, now we're on that planet we were talking about". If they just jumped to them walking around on the planet, the transition is too awkward and B-movie-ish.

And when you're using a soundstage, people expect the shuttlecraft to be shown in a DIFFERENT establishing shot of a landing area. That's expensive because a soundstage is a small place and only has a few angles it can work in, and it's only one location. It'll be awkward to step out of the shuttlecraft prop, walk 5 feet, and say "here are the incredibly rare crystals we were looking for, Captain... we're in luck, as always."

Thus the transporter was born. 2 seconds of stock effect and we've completed a theatrical transition.

Sadly yeah, teleportation is almost certainly completely impossible. To reconstitute a brain you would have to reconstitute not only the cells but electrical charges and stuff. I hate to say never but it's never going to happen. You could jump through a wormhole or pop into hyperspace, of course. Much easier than true teleportation.

What I found as a "well then what's the point" is FTFA:
"In an active feed-forward protocol, conventional data is sent alongside the quantum information, enabling the recipient to decipher the transferred signal with a higher efficiency."

Does that mean there's also a standard type of transmission in parallel? If so, then why bother with the quantum action at a distance for the transmission.?
