The Viterbi Algorithm and Quantum Communications

Posted by ScuttleMonkey on from the sneaky-states dept.

eldavojohn writes "There have been a lot of tests in using quantum mechanics to communicate across large distances. But a student & a professor at USC have proven that the Viterbi algorithm can be applied to quantum communication. In the traditional Alice sends Bob a message scenario, 'Bob can reliably spot errors, and knows which message qubits are bogus before he opens the message — crucial, because opening it destroys it; and if it is garbled, he has nothing.'"

    I wish Alice and Bob would just go ahead and do it already. Everybody knows they have the hots for one another.

      Kids these days. When will they learn that its not worth the risk. Safe encryption should be practised all the time, not just when you feel like it.

    And for that matter what is the chance Alice will just say it once?

    Go ask Alice. I think she'll know.

    So you're suggesting Bob and Alice get entangled? That's spooky... too bad we wouldn't be able to watch.
