The Star Trek transporter would be the best solution. Who wants to be the first human to try it out?
Also, disassembling someone and beaming them would take a significant amount of power, so we have to harness the matter/antimatter thing first.
Transporter seems to be the wrong name for that particular piece of kit. It doesn't really transport anything; it destroys the original and recreates it somewhere else. Legally, if you used a transporter, you would be dead, and the thing now claiming to be you would be a machine-made imposter.
Dr McCoy explains the process (in Spock Must Die!
by James Blish) as follows:
...the effect of the transporter is to dissolve my body and reassemble it somewhere else.
at the other end, a body is assembled which is apparently identical with the original, is alive, has consciousness, and has all the memories of the original. But it is NOT the original. That has been destroyed.
I am, by definition, not the same man who went into a transporter for the first time twenty years ago. I am a construct made by a machine after the image of a dead man - and the hell of it is, not even I can know how exact the imitation is, because - well, because obviously if anything is missing I wouldn't remember it.
