An anonymous reader writes "Scientists at the Kavli Institute of Nanoscience say they've managed to reliably teleport quantum information stored in one bit of diamond to another sitting three meters away (abstract, pre-print) . Now, their goal is to extend the range over a distance of a kilometer. '[R]eliability of quantum teleportation has been elusive. For example, in 2009, University of Maryland physicists demonstrated the transfer of quantum information, but only one of every 100 million attempts succeeded, meaning that transferring a single bit of quantum information required roughly 10 minutes. In contrast, the scientists at Delft have achieved the ability "deterministically," meaning they can now teleport the quantum state of two entangled electrons accurately 100 percent of the time. They did so by producing qubits using electrons trapped in diamonds at extremely low temperatures. According to Dr. Hanson, the diamonds effectively create 'miniprisons' in which the electrons were held. The researchers were able to establish a spin, or value, for electrons, and then read the value reliably.'"
