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
