"Although teleportation is associated with the science-fiction series Star Trek, no one is likely to be beamed anywhere soon.
But the achievement of Polzik's team, in collaboration with the theorist Ignacio Cirac of the Max Planck Institute for Quantum Optics in Garching, Germany, marks an advancement in the field of quantum information and computers, which could transmit and process information in a way that was impossible before.
"It is really about teleporting information from one site to another site. Quantum information is different from classical information in the sense that it cannot be measured. It has much higher information capacity and it cannot be eavesdropped on. The transmission of quantum information can be made unconditionally secure," said Polzik whose research is reported in the journal Nature.
Quantum computing requires manipulation of information contained in the quantum states, which include physical properties such as energy, motion and magnetic field, of the atoms.
"Creating entanglement is a very important step but there are two more steps at least to perform teleportation. We have succeeded in making all three steps -- that is entanglement, quantum measurement and quantum feedback," he added."
Well, here at Mudcat we have the entanglement part down to a fine art. Although it does seem that the entanglement hereabouts is inversely proportional to the quality of the information, but maybe that's a quantum thing. :)
