Quantum Information Can be Negative

Posted by timothy on from the you-are-now-dumber dept.

nerdlygirl writes "In a development that would probably even puzzle Claude Shannon, information can be negative -- at least when the information is quantum. The discovery, by Horodecki, Oppenheim, and Winter, appears in the current edition of the leading journal Nature. If I tell you negative information, you'll know less. Apparently, researchers hope to use this to gain deeper insights into phenomena such as quantum teleportation and computation, as well as the very structure of the quantum world. More details can be found here and here A popular account of the article can be found on Oppenheim's homepage, and a free version of the article can be found in the arxiv for those of us without subscriptions to Nature."

    a) Ah, so that's what's been coming out of the White House all this time.

    b) If I commit, is it really a rollback?

    Negative information has been known about for some time. A study at the University of Maryland revealed its existence in the media realm a couple years ago.

  4. Most political ads are negative information by BroncoInCalifornia · · Score: 0, Offtopic
    Karl Rove does not have a monopoly on negative information.

    Nearly all political ads on TV leave the viewer even less informed!

    I am glad to see there is a theoretical basis for this in quantum mechanics.
