[quant-ph/0505062] Quantum information can be negative

In the classical case, partial information must always be positive, but we find that in the quantum world this physical quantity can be negative. If the partial information is positive, its sender needs to communicate this number of quantum bits to the receiver; if it is negative, the sender and receiver instead gain the corresponding potential for future quantum communication.

Wow... now I really want to go get a degree in quantum mechanics...
