Erik,
Interesting and original approach. Nicely written. Do you consider reversing a reversible physical process to return a state to it's previous condition, has any parallel with time reversal? e.g.
Take a polarising interaction; absorption/re-emission where the polariser electron has some polarity and changes the state interacting with it, which is what's found (i.e. Zeilinger ref in my essay, where it has 'no memory of it's previous state'). An inverse electron polarity, at the photomultiplier for instance, could then return it to it's original state (or the same one repeated just 'square' the new amplitude).
Sorry that got a bit complicated! But do you think states can revert (or keep being changed) while time just ticks on in no particular 'direction'?
I've suggested it can and show in my essay that seems to bring exceptional resolving power!
Nicely done for yours.
Very best
Peter
