Have you actually read the full article (and not just the popular description)?? Because it sure doesn't sound like it, and I have no idea why you got modded up. I am also a quantum physicist (I wasn't going to pull that out, but you have).
Even from just the abstract -- they determine how much quantum communication is needed to transfer a shared state to one system (this is one way to determine the partial information). They find that the amount of communication can be negative (the state is transfered and the potential for future communication is gained). That blows my mind, and I'm used to this stuff. You should try approaching it with an open mind, and joy of discovery.
Nature doesn't publish things in their letters section unless the result is really heavy hitting and solid.
Hardly. The concept of information in the quantum case is well defined, and has been for ages. No where do they appeal to information in everyday life, except on some webpage where they try to explain it to people.
FTFA: "It sometimes seems that we become more ignorant after talking to certain individuals. Perhaps they are saying things which are confusing or untrue. Well, after getting negative information, you know less. But not in the same sense as someone who tells you lies are tries to bamboozle you. Remember, that we don't worry about the quality of information (whether it is true or false for example). We just concern ourselves with how much there is. So, if we know less after receiving negative information, the amount of information we have must actually go down. This obviously cannot happen classically, but let me try to explain why it can happen quantumly."
