Teleportation goes long distance
Monday, August 23, 2004 by BX | Discussion: WinCustomize News
Physicists have carried out successful teleportation with particles of light over a distance of 600m across the River Danube in Austria.
When physicists say "teleportation", they are describing the transfer of key properties from one particle to another without a physical link.
Long distance teleportation is crucial if dreams of superfast quantum computing are to be realised.
Researchers from the University of Vienna and the Austrian Academy of Science used an 800m-long optical fibre fed through a public sewer system tunnel to connect labs on opposite sides of the River Danube.
The link establishes a channel between the labs, dubbed Alice and Bob. This enables the properties, or "quantum states", of light particles to be transferred between the sender (Alice) and the receiver (Bob).

Arrgh, Captain im too fat, I can't reach the button ! 
So they finaly made a Cut and Paste machine

One step closer to quantum computers and quantum encrpyted communications. 
UQ, IBM, even BT is doing research in this area. Fusion reactors, Superconductivity, ScramJet, Nanotechnology the research is starting to get fast paced.
