I am a postdoc with an interest in applications of operator algebra to local quantum physics. I am also interested in topological qauntum computing and their relation to tensor categories.

comment Which QFTs were rigorously constructed?
@Squark: I don't think Wightman axioms are too restrictive. Haag-Kastler is just easier to work with. Under suitable technical assumptions one can go from one to the other and back.

Ok thanks Ron! I'll keep that in mind.

Thanks! Our library unfortunately doesn't have the book, but the articles look interesting.

comment What is the use of a Universal-NOT gate?
The article you cite is already mentioned in the question. It's the preprint of the Phys Rev A article.

comment Status of local gauge invariance in axiomatic quantum field theory
Just a comment for this moment: in a preprint by Ciolli and Ruzzi that appeared on the arxiv today (1109.4824) they make a remark that progress towards the description of massless particles in AQFT is underway. They refer to a recent talk by Doplicher, which unfortunately I have missed this talk so I cannot comment on this.
