16 June, 2004, BBC News: Teleportation breakthrough made Citat: "...What the teams at the University of Innsbruck and the US National Institute of Standards and Technology (Nist) did was teleport qubits [ kvantecomputer beregningsenhed] 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"..."
Physics Web, 17 Mar 2000, Quantum leap for entanglement Citat: "...Entanglement is one of the most mysterious and fundamental properties of quantum mechanics. When two or more particles are "entangled", the wavefunction describing them cannot be factorized into a product of single-particle wavefunctions. This means that a measurement on one particle will immediately influence the state of the other particles in the entangled system. A group of physicists in the US has now "entangled" four particles for the first time (Nature 404 256)..."
Webarchive backup: The Quantum World, EPR:- Spooky Connections (entanglement) Citat: "...Quantum theory upset Einstein because it gave him nothing better to grapple with than frustrating probabilities. In 1936, he got together with Boris Podolsky and Nathan Rosen to create the "EPR paradox". It's ironic that the spooky EPR connection has now been used in the lab to teleport photons, because the original reason for inventing the EPR paradox was to show that one of the implications of quantum theory was so unacceptable that it must be wrong or incomplete in some respect...."
