Hej Mogens

16 June, 2004, BBC News: Teleportation breakthrough made:
http://news.bbc.co.uk/1/hi/sci/tech/3811785.stm
Citat: "...What the teams at the University of Innsbruck and the US
National Institute of Standards and Technology (Nist) did was teleport
qubits from one atom to another with the help of a third auxiliary
atom...The teleportation took place in milliseconds and at the push of a
button, the first time such a deterministic mechanism has been developed
for the process...The landmark experiments are being viewed as a major
advance in the quest to achieve ultra-fast computers, inside which
teleportation could provide a form of invisible "quantum wiring"..."
