I'm not a scientific expert and don't pretend to know about teleportation experimentation, but found this article interesting. Can anyone shed some
more light on it?
Jan. 31 ó From an idea that was only considered practicable 10 years ago, scientists say they have succeeded in teleporting laser photons over two
kilometers (1.25 miles), the biggest distance yet achieved. In science fiction, teleportation entails taking someone and creating a replica of him or
her a long distance away, and destroying the original. It remained confined to pulp literature until a decade ago. The perceived barrier to it was
something called the Heisenberg Uncertainty Principle. This principle states that the more accurately you try to scan or measure an atom or other
object in order to teleport it, the more you disrupt its original quantum state, and so you cannot create a true replica.
Things changed in 1993 with a landmark paper by a team led by an IBM scientist, Charles Bennett, who thought up a way of getting around this problem
using photons, or particles of light, as the object to be transported.
Their answer was to exploit something called "quantum entanglement," in which a laser beam is squeezed and split in such a way that it creates two
particles of light at the same time.
Particles created in this exotic process behave like psychic twins. Even if they are far apart, a disturbance to one particle affects the other, a
phenomenon once dubbed "spooky interaction" by Einstein.
The first concrete results from this idea began emerging in 1997, with a couple of labs in Europe and the United States transporting a small unit of
information, called a quantum bit (qubit), a distance of about one meter (3.25 feet).
But, in a study reported Thursday in the British weekly journal Nature, scientists at the University of Geneva, Switzerland, and the University of
Aarhus, Denmark, have teleported data to another lab 55 meters (178 feet) away through a 2-kilometer (1.25-mile) roll of standard fibre-optic cable.
