I believe the answer is:

teleport

(Other definitions for teleport that I've seen before include "Sci-fi travel device" , "Sci-fi transporter" , "Move by dematerialising and re-assembling - repel tot (anag)" , "Move instantly across space (in science fiction)" , "Travel instantly (sci-fi)" .)

I've seen this clue in The Washington Post.
