I think that formalising and explaining as many useful diagramming conventions as possible is an Azimuth goal. Do you know any good descriptions of quantum circuit diagrams, The Wikipedia entry is cursory and searching didn't come up with anything useful. How these relate to the Penrose notation which I could just about grasp in the Emperor's new clothes. I don't think that there's a guide to ladder diagrams which had struck me as another omission which I'm not the best person to write either.
I guess it's also off topic wrt. clustering techniques but I'd also like to know about how you specify applications for use with QIT?
Thanks for the reminder that Penrose notation exists.
