==Origin==
The use of the term ''teleport'' to describe the [[hypothetical]] movement of material objects between one place and another without physically traversing the [[distance]] between them has been documented as early as 1878.
American writer [https://en.wikipedia.org/wiki/Charles_Fort Charles Fort] is credited with having coined the word teleportation in 1931 to describe the [[strange]] disappearances and appearances of anomalies, which he suggested may be connected. As in the earlier usage, he joined the [[Greek]] prefix tele- (meaning "distant") to the root of the [[Latin]] verb ''portare'' (meaning "to carry"). Fort's first formal use of the [[word]] occurred in the second chapter of his 1931 book [https://en.wikipedia.org/wiki/Lo! ''Lo!'']:
<blockquote>Mostly in this [[book]] I shall specialize upon indications that there exists a transportory [[force]] that I shall call Teleportation. I shall be accused of having assembled lies, yarns, hoaxes, and [[superstitions]]. To some degree I think so, myself. To some degree, I do not. I offer the data.</blockquote>

*1: the [[act]] or [[process]] of moving an object or person by [[psychokinesis]]
*2: in [[fiction]] : instantaeous travel between two locations without crossing the intervening [[space]]
==Description==
'''Teleportation''' or teletransportation is the theoretical transfer of [[matter]] or [[energy]] from one point to another without traversing the physical [[space]] between them. It is a common subject in [[science fiction]] literature, film, video games, and television.
Since 1993, teleportation has become a hot topic in [[quantum mechanics]], namely state, energy and particle teleportation.
Scientists believe it is not possible to teleport macroscopic objects such as [[human being]]s, but there may be teleportation in the microscopic world. Three possible kinds of teleportation in quantum mechanics and quantum electrodynamics have been proposed: state teleportation, energy teleportation, and [[particle]] teleportation.
In 1993, Bennett et al proposed that a quantum state of a particle could be teleported to another distant [[particle]], but the two particles do not move at all. This is called state teleportation. There are a lot of following theoretical and [[experimental]] papers published. [[Researchers]] believe that quantum teleportation is the foundation of quantum calculation and quantum communication.
In 2008, M. Hotta proposed that it may be possible to teleport energy by [[exploiting]] quantum energy fluctuations of an entangled [[vacuum]] state of a quantum field. There are some papers published but no experimental verification.
In 2016, Y. Wei proposed that particles themselves could teleport from one place to another. This is called particle teleportation. With this [[concept]], [[Superconductivity]] can be viewed as the teleportation of some [[electrons]] in the superconductor and superfluidity as the teleportation of some of the atoms in the cellular tube. Physicists are trying to verify this concept experimentally.
