Are there any applications of quantum information theory to physics?

I guess they have similar mathematical structures. That's all. But let's see what the experts say about this. – user1355 Feb 23 '11 at 10:52
Only that information underlies all of physics, including that of black holes ;) – user346 Feb 23 '11 at 12:42
@Deepak: I thought physics underlies all of information. So there, we have a proof of equivalence :) – Marek Feb 23 '11 at 16:34
The "What do you think" part of your question was just an invitation to discussion, not an actual question, so I removed it. You can re-edit if you can make a more specific phrasing: ask a specific question that can be answered, don't just solicit people's opinions. – David Z Feb 23 '11 at 17:22
I published a paper applying the quantum information idea "mutually unbiased bases" to the problem of understanding the relationship between spin and the generations of elementary particles, see So my own opinion is that there is a relationship. In general, physics has advanced partly by improvements in the theoretical understanding of fundamental ideas and partly by experiments which cause the rejection of previously held beliefs. – Carl Brannen Feb 24 '11 at 1:00

There's a huge body of literature in applying ideas from quantum information to the study of strongly interacting many body systems. If I have time I'll edit this answer with my own personal review (primarily all of the lovely simulation techniques that QIT has given a solid physical and conceptual foundation to) but as a jumping off point, there is a set of lecture notes with excellent references here.
