In 2004 I graduated from Waterloo where I was a member of the Perimeter Institute and worked with Lucien Hardy on a problem in quantum automata theory. I then started reading Baez, Coecke and Isham and decided I wanted to do category theory. In 2008 I started at McGill where I was a research assistant to Dr Panangaden and worked on both categorical quantum mechanics and the quantum causal dynamics. Now I am attempting to provide novel uses of the theory of categories for physics and economics. Also, I am interested in the concept of "idealization of structure" where compact elements in a collection of categories express this. I have several posts at the nforum where I talk about more pure mathematical ideas.

comment fixed input qubit state to an arbirary pure state using two variable rotations and one fixed rotation
David, thank you, yes I think the problem is the same. I just need some help in writing down a form for the operation (unitary transformation or Euler rotation) that highlights the order of operations. I, myself, can't derive the form by hand.

comment decoherence free subspace of a single photon
I am thinking of fiber optic spans. The most likely cause of decoherence is second order polarization mode dispersion. There are no treatments of this subject in terms of a joint frequency and polarization linear operator. If you know of one, that would help. Generally, frequency is taken as a classical variable.
