A Quantum Memory Leap

January 23, 2009 | Source: Technology Review

University of Maryland and University of Michigan researchers have announced the ghostly transfer of the quantum state of a single ion to another one a meter away for several seconds.

Unlike current experiments, this scheme for “quantum teleportation” could buy enough time for manipulations that allow long-distance communications that are immune to eavesdropping, or for computations that exploit the quantum mechanics to perform blazing fast calculations.
