Violation of Heisenberg's Uncertainty Principle

Posted by Soulskill on from the kinda-sorta dept.

mbone writes "A very interesting paper (PDF) has just hit the streets (or, at least, Physics Review Letters) about the Heisenberg uncertainty relationship as it was originally formulated about measurements. The researchers find that they can exceed the uncertainty limit in measurements (although the uncertainty limit in quantum states is still followed, so the foundations of quantum mechanics still appear to be sound.) This is really an attack on quantum entanglement (the correlations imposed between two related particles), and so may have immediate applications in cracking quantum cryptography systems. It may also be easier to read quantum communications without being detected than people originally thought."

    I learned about it on the factual science TV show (currently honored on Google.com), Star Trek. They need a Heisenberg compensator.

      No, they need to *uncouple* the heisenberg compensator. *Everybody* knows that.

    Are they sure about that? I think they fe-line to us.

    You won't know whether it still works unless you open the box.
