Wikipedia
A jump drive is a speculative method of traveling faster than light (FTL) in science fiction. Related concepts are hyperdrive, warp drive and interstellar teleporter. The key characteristic of a jump drive (as the term is usually used) is that it allows a starship to be instantaneously teleported between two points. A jump drive is supposed to make a spaceship (or any matter) go from one point in space to another point, which may be several light years away, in a single instant. Like time travel, a jump drive is often taken for granted in science fiction, but very few science fiction works talk about the mechanics behind a jump drive. There are vague indications of the involvement of tachyons and the space-time continuum in some works.
