The question of explaining the classicality of the everyday world becomes the question of whether one can derive from within quantum mechanics the conditions necessary to discover and practise quantum mechanics itself, and thus, in Shimony's
Section 3 analyses the claim that decoherence solves the measurement problem, as well as the broadening of the problem through the inclusion of environmental interactions, the idea of emergence of classicality, and the motivation for discussing decoherence together with approaches to the foundations of quantum mechanics.
Even more generally, one could ask whether the results of decoherence could thus be used to explain the emergence of the entire classicality of the everyday world, i.e., to explain both kinematical features such as macroscopic localisation and dynamical features such as approximately Newtonian or Brownian trajectories, whenever they happen to be phenomenologically adequate descriptions.
It is by now widely recognized that this non-locality is the principal locus of non-classicality in quantum (and more general) probability models.
On the other hand, in order to assess the programme of explaining the emergence of classicality using decoherence (together with appropriate foundational approaches), one has to probe how far the applications of decoherence can be pushed.
Even though neither Borel test spaces nor quantum test spaces are semi-classical, one might argue that in any real laboratory situation, semi-classicality is the rule.
The situation is more subtle: chaos magnifies any uncertainty, but in the quantum case h has a smoothing effect, which would suppress chaos if this suppression were not itself suppressed by externally-induced decoherence, that restores classicality (including chaos if the classical orbits are unstable).
In doing so, we emphasize the distinct notions of the problem of classicality in the ensemble interpretation of quantum mechanics and in decoherence-based approaches that are aimed at addressing the measurement problem. can someone sort this out for me?
Lastly, Mr Feeder said, he had better not refer to the festive occasion, in the hearing of Doctor and Mrs Blimber; as these preliminaries, and the whole of the arrangements, were conducted on principles of classicality and high breeding; and that Doctor and Mrs
She has a fine face — originally of a character that would be rather called very pretty than handsome, but improved into classicality by the acquired expression of her fashionable state.
