From CNET, physicists in Denmark have teleported information from light to matter, bringing quantum communication and computing closer to reality. The experiment involved, for the first time, a macroscopic atomic object containing thousands of billions of atoms. They also teleported the information a distance of half a meter, but believe it can be extended further.
"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," Professor Eugene Polzik added. He and his team at the Niels Bohr Institute at the University of Copenhagen in Denmark made the advance. "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."
