Scientists "Teleport" Quantum Information One Meter 107

the4thdimension writes "While we may not be beaming up to the Enterprise anytime soon, a team of scientists from the University of Maryland and the University of Michigan have managed to teleport information between two atoms up to a meter apart. Until this point, only very tiny distances were able to be traveled. However, using a complicated system of photons, ions, lasers, and electromagnetics, scientists have managed to 'teleport' information contained on one atom to another atom that is in a separate sealed container. This can lead to a wide range of developments in computing and communications."

    Yeah, it seems like every so often, there's another story in the media that "teleportation has been achieved," or "we can make things invisible," or "scientists have made light go faster than light." They go on to explain all the great things we could do if we could teleport things, go faster than light, and make things invisible.

    Then, down near the bottom somewhere, they finally explain that no, we're not talking about real teleportation, but rather quantum entanglement that can't really be used for communication. We're not talking about real faster-than-light travel, but making a light wave that sort of looks like it's going faster than light but isn't. We're talking about something that might be useful for stealth airplanes, making them invisible to radar, and not real invisibility. Stuff like that.

    And then they tag some throw-away line at the end like, "But who knows, maybe we'll be able to teleport to the moon next year!"

    I hate journalists.
