Negative Quantum Information.

[swestrup]

According to this slashdot article, quantum information can be negative. I find it impossible to stress how much of modern physics can be derived from information theory, so this whole concept boggles me. If there are genuine ways to exploit this phenomenon then it could change everything. On the other hand, it may turn out to be nothing more than a curiosity, like negative absolute temperatures, with no real impact. I find I have no good insight for which it will be.
