Re:At least one (Score 3, Informative)

I am also a researcher near to this field, and actually heard it presented at a conference a few months back. The reaction of the people I know (who actively do research in this area, more so than myself), was one of extreme excitement. I think perhaps you don't understand the result.

Quantum information is not a question of interpretation -- it is well known what it is, in terms of communication theory. What these guys did, is prove how much communication was required to send information, if the receiver already had some of it. No one knew how to calculate this, much less knew that it could be negative. I can't fathom why you would consider this a matter of interpretation. It is a complex mathematical calculation.
