Fiction

Teleportation is a common subject in science fiction literature, film, video games, and television. The use of matter transmitters in science fiction originated at least as early as the 19th century. An early example of scientific teleportation (as opposed to magical or spiritual teleportation) is found in the 1897 novel '' To Venus in Five Seconds'' by Fred T. Jane. Jane's protagonist is transported from a strange-machinery-containing

Live performance

Teleportation illusions have featured in live performances throughout history, often under the fiction of miracles, psychic phenomenon, or magic. The cups and balls trick has been performed since 3 BC and can involve balls vanishing, reappearing, teleporting and transposing (objects in two locations interchanging places). A common trick of close-up magic is the apparent teleportation of a small object, such as a marked playing card, which can involve sleight-of-hand, misdirection, and pickpocketing. Magic shows were popular entertainments at

carrier propagating between the two. In 1993, Bennett ''et al'' proposed that a quantum state of a particle could be transferred to another distant particle, without moving the two particles at all. This is called quantum state teleportation. There are many following theoretical and experimental papers published. In 2008, M. Hotta proposed that it may be possible to teleport energy by exploiting quantum energy fluctuations of an entangled

. In 2014, researcher Ronald Hanson and colleagues from the Technical University Delft in the Netherlands, demonstrated the teleportation of information between two entangled quantumbits three metres apart. A generalization of quantum mechanics suggests particles could be teleported from one place to another. This is called particle teleportation. With this concept,

as the teleportation of some of the atoms in the cellular tube. Further analysis shows that the teleportation time increases with the square root of mass and longer teleportation times require sustained quantum coherence. While particle teleportation may be feasible for an electron, a proton may not be feasible.
