"Spooky" Science Points Towards Quantum Computing

Stony Stevenson writes to tell us that University of Michigan physicists have been able to establish an "entanglement" between two atoms trapped more than a meter apart in different enclosures using light. This shows how two different atoms can have a sort of communication, something Einstein referred to as 'spooky action-at-a-distance'. "By manipulating the photons emitted from each of the two atoms and guiding them to interact along a fibre-optic thread, the researchers were able to detect the resulting photon clicks and entangle the atoms. Professor Monroe explained that the fibre-optic thread was necessary to establish entanglement of the atoms. But the fibre could be severed and the two atoms would remain entangled, even if one were 'carefully taken to Jupiter'."

    No problem with the entanglement and all, but what Michigan really needs to figure out is how to score a touchdown at a distance...

    Why always Einstein?

    Einstein invented blablabla.
    Einstein invented blobloblo.
    Einstein invented blublublu.
    Einstein invented blebleble.
    Einstein invented bliblibli.

    The Einstein's theories were relativistic.
    Why the Quantum theories that opposes to the Relativity theories are from Einstein?

    How many secrets has the died Einstein now?

    Nice! i would mod you up if i had points!
