Teleportation Achievable?

I've always found the idea of teleportation as an object that is dematerialized and rematerialized in a different location.

With our current technology, we are only able to teleport very miniscule objects.

As for teleportation of an organism, I'm not sure we will be able to find a method of teleportation for a long, long time (at least not before hover cars).

 

Well worm holes in some sense can be considered teleportation so yes I do believe it is possible.

 

I can't see it happening but a century ago did people think that we would have iPhones?

 

here you're assuming wormholes exist and are possible to utilize for any kind of relatively safe travel. so far, wormholes have been observed to exist only in science fiction.

the problems with this are:
-you cannot make identical copies of quantum mechanical systems (no-cloning theorem)
-you cannot transmit the information of a quantum state precisely through classical means (no-teleportation theorem, a consequence of no-cloning theorem)

the only way to make this work is to have an equal amount of matter A' that you want to teleport entangled with the original matter A (an issue larger the more larger your object is), so you can use fancy quantum information science shenanigans combined with classical communication to essentially destroy the original quantum states of A and have the identical states appear in A'.

the problem with this approach is that you then have to move the entangled matter -classically- wherever you want to teleport the information to, without collapsing the entangled state, (a huge issue even with small objects, even huger with larger ones) which sort of ruins the whole point.

on the other hand, if you're okay with not preserving the quantum states, there's no theoretical barrier stopping you from recording what molecules matter is formed from and in what way, and then transmitting that information classically. how this would affect biological matter i don't know, i'm not a molecular biologist. on the other hand, if something like this turns out to be correct, you'd just get a dead human.


tl;dr: perfect teleportation (quantum information intact) of matter is an extremely unpractical since it requires in addition to mindbogglingly major technological advancements moving a bunch of matter to the teleport destination, and using classical, speed-of-light-limited communication afterwards: you'd better be off just moving the original matter. if you're willing to go with imperfect teleportation (classical information only), it may or may not result in corpses.

 

No, because it would defy the law of gravity which is always there and will ALWAYS be there.

 

That is a good point..

 

An object which is on one pair of co-ordinates moving to another seems highly unlikely without actually moving. Thus it's kinda impossible.
