::::::The kinds of experiments we shall consider are limited in the following respects: they are repeatable; there is a clear distinction between the state preparation device and the detection and registration device; and - this the most important limitation - we assume that for a given state-preparation device, preparing the system to be measured in a definite initial state, the state can be resolved into ''channels'', each of which can be independently blocked, in such a way that when only one channel is open the outcome of the experiment is ''deterministic'' - in the sense that if there is any registered outcome at all (on repetition of the experiment) it is always the ''same'' outcome.<ref>[[Simon Saunders|Saunders, S.]] (2004).

:But anyway, here's a start. "How do you characterize a "maximal commuting set of observables"?" I think this is standard phrasing, at least in some places. One starts with some choice of observable. Then one chooses another. If they commute, it stays; if they don't, it's out. Repeat until one can't find any more that commute. I suppose that seems rather rough and ready, and hardly convincing. I will forthwith have a look to check this. Or is this utterly missing the point?[[User:Chjoaygame|Chjoaygame]] ([[User talk:Chjoaygame|talk]]) 11:05, 10 February 2016 (UTC)
