Quantum computers may lead to practical teleportation technology

Thursday, January 29, 2009

“The current experiment marks the first in which information has traveled a significant distance — 1 meter, or a little more than 3 ft. — between two isolated atoms. ..An ultrafast laser pulse triggers the atoms to emit photons simultaneously. If the photons interact in just the right way, their parent atoms enter a quantum state known as entanglement, in which atom B adopts the properties of atom A even though they’re in separate chambers a meter apart. When A is measured, the information that had been previously encoded on it disappears in accordance with the quirky rules of the quantum world. But all is not lost: Because B is entangled with A, B now contains the information that was once carried on A. That information, in a very real sense, has been teleported.”

    We're supposed to believe the super-science behind quantum teleportation, and yet they don't know a meter is a little more than three feet. Color me unimpressed.

    Never mind. They fixed it. They're still a bunch of morons, but at least they had someone who knew how to count to three.
