Quantum teleportation

Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. how this is accomplished is usually not explained in detail but the general idea seems to he that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original. a teleportation machine would be like a fax machine, except that it would work on 3-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.

In 1993 an international group of six scientists including IBM fellow charles h. bennett, confirmed the institution of the majority of science function writers by showing that perfect teleportation is indeed possible in principle, but only if the original is destroyed, meanwhile, other scientists are planning fiction experiments to demonstrate teleportation in microscopic objects, such as single atoms or photons, in the next few years. but science location fans will he disappointed to learn that no one expects to be able to teleport people or other macroscopic objects in the foreseeable future, for a variety of engineering reasons, even though it would not violate any fundamental law to do so
