Um, forget teleportation, in our lifetime. (Even then, forget trying to convince me to do it.)
Assuming it were possible to detect and record every atomic particle of a human being (which it isn't, according to the Heisenberg uncertainty principle), it would take more energy than (iirc) the sun discharges over several (hours / days / months - can't remember, but it was more than is feasible to store) and a lens with a focal length greater than the Earth's diameter to detect the particles which are sub-visible lengths of lightwave).
Warp drive may be possible in a different form, certainly ain't going to get anything bigger than a small molecule to reach the speed of light, let alone a ship.

But advanced science is no more explainable than magic, to someone unfamiliar with th technology.
Try explaining how a refrigerator works to a medieval serf.
