Continuing with that Star Trek theme, Scientists have succeeded in 'teleporting' photons. In the December 11 1997 issue of Nature, Anton Zeilinger and colleagues
at the University of Innsbruck, Austria, demonstrated their ability to destroy and recreate bits of light. Utilizing Quantum Teleportation, and idea that even Einstein
thought was impossible, destroyed massless photons, and in the process transferring information about a physical characteristic of the photons. Other photons picked
up this information and took on the characteristic, thus becoming replicas of the original bits of light.
There are obviously significant differences between the Star Trek transporter and the technology demonstrated by the Austrian physicists. The demonstration
described only dealt with massless photons. It may be quite a while before we can avoid all that traffic on the way to work by 'beaming.' Herr Zeilinger says that
teleportation of individual atoms and molecules is only a few years off. However, "teleportation of complex living beings, even bacteria, is so far away technologically
that it's not really worth thinking about it," said IBM physicist Charles Bennett, one of the original proposers of the technology.
