Formalization of Bohr’s Contextuality Within the Theory of Open Quantum Systems

In quantum physics, the notion of contextuality has a variety interpretations, which are typically associated with names their inventors, say, Bohr, Bell, Kochen, Specker, and recently Dzhafarov. fact, Bohr was first who pointed to measurements as part formulation his principle complementarity. (Instead “contextuality,” he considered dependence on “experimental conditions.”) Unfortunately, counterpart complementarity overshadowed by issue incompatibility observables. The interest for rose again only in connection Bell inequality. original Bohr’s contextuality, each measurement, practically forgotten. It highlighted our works applications both physics cognition. this note, theory open systems is applied formalization within framework indirect measurements. This scheme widely used information leads Davis–Lewis–Ozawa instruments. scheme, viewpoint represented formal mathematical framework.
