    I would like to contribute to the nLab page on state spaces. In particular I would like to build up to this through a particular route, for which I will need some help. I have been trying to build a notion of state space out of a monad. I have found a paper where a state space is built from a comonad. The paper in particular is Vicary’s work on the quantum harmonic oscillator. The adjunction F=RQF = RQ in section 4.1, he calls a state space for multi-particle system or Fock space. This FF is a comonad. I guess, in short, could we put up an article for comonads as state spaces?
