Does quantum dynamics apply to an idealization of nature opposite to the ideal of classical dynamics?

The relation between quantum dynamics and classical dynamics is considered from the perspective of an experimentalist. Since noise is present in all measurements, experimental results cannot be exact, but have a finite uncertainty. Accordingly, the deterministic dynamic theories do not describe some reality, but idealizations of nature. The idealization of quantum dynamics is different from the idealization of classical dynamics. The objects of the two theories are subject to different idealized conditions. The objects of classical dynamics are observable continuously, whereas the objects of quantum dynamics are unobservable.
