Can macro quantum entanglement make teleportation possible?? i had a kind of hypothesis...that if we entangle each and every particle of a human body with other particles which are at the destination then can't we make the person teleport at the destination by sending his body's quantum information there through entanglement??

But doesn't that require making a complete copy of the particles here first?

Wormholes in General Relativity may be the best way to teleport macroscopic objects. Once we understand quantum gravity. It won't require the energy of an entire solar system to build wormhole between say US and UK, but merely by reprogramming the differential manifold and adjustment of the Einstein Field Equation. Another is to quantum tunnel spacetime points itself. That way, (perhaps) the entire particles can be transported, not just transfer the quantum state but the particle itself.

quantum entanglement does make teleportation possible.
unfortunately, quantum entanglement of an entire person would be incredibly difficult, maybe impossible (due to decoherence). It's an interesting question though.

Entanglement enables the copying of the quantum states of a particle in spite of the "no cloning" rule. Some information must be transmitted classically however so there in no "get out of jail free" card from Relativity.

i am aware about decoherence...but if somehow we can overcome it...(i mean theoretically)...wont that make teleportation possible then through quantum entanglement...i think its an interesting field to do research...

There was some discussion of how it would in principle be possible to quantum teleport macro objects (though probably impossible in practice) on this thread, and I linked to a Scientific American article by a quantum physicist which has some illustrations of how it would work:

See for example the Scientific American article by Anton Zeilinger (a physicist known for his work in quantum teleportation, among other subjects) which starts on p. 9 http://www.scribd.com/doc/47422884/Extreme-Physics-Scientific-American-February-2004 , the illustrations at the bottom of pp. 10-13 show conceptually how quantum teleportation would work for a macro object like a person (they note this is "impossible in practice but a good example to aid the imagination"), and the "Skeptic's Corner" sidebar on p. 15 where "the author answers common teleportation questions" seems to say that the problems with teleportation of macro objects are practical ones like preventing decoherence and storing the vast amount of classical information that would be needed, but doesn't suggest any fundamental theoretical problems with the idea

pretty good article. I guess it might be possible in theory, but practically impossible at the moment.
