Teleportation is the name given by science fiction writers to the feat of making an object or a person disintegrate in one place while a perfect replica appears some where else. A teleportation machine would be like fax machine except that it would work on three dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. Teleportation was not taken seriously by scientists, because it was thought to violate the uncertainty principle of quantum mechanics, which forbids any measuring or scanning process from extracting all the information in an atom or other object.
Scientists found a way to make and end-run around this logic, using a celebrated and paradoxical feature of quantum mechanics known as the Einstein-Podolsky-Rosen effect. The future is promising that we can even teleport man.Teleportation involves dematerializing an object at one point, and sending the details of that object's precise atomic configuration to another location, where it will be reconstructed. What this means is that time and space could be eliminated from travel - we could be transported to any location instantly, without actually crossing a physical distance.
Most of us were introduced to the idea of teleportation, and other futuristic technologies, by the short-lived star Trek television series (1966-69) based on tales written by Gene Roddenberry. In 1993, the idea of teleportation moved out of the realm of science fiction and into the world of theoretical possibility. It was then that physicist Charles Bennett and a team of researchers at IBM confirmed that quantum teleportation was possible, but only if the original object being teleported was destroyed.Before going into more detail about the teleportation experiments performed to date, let us firstly get a better idea about what teleportation actually is.
