We argue that Anton Zeilinger's "foundational conceptual principle" for quantum mechanics according to which an elementary system carries one bit of information is an idealistic principle, which should be replaced by a realistic principle of contextuality. Specific properties of quantum systems are a consequence of impossibility to speak about them without reference to the tools of their observation/identification and, consequently, context in which these tools are applied.

The Nobel committee announced on October 4th that Alain Aspect, John Clauser and Anton Zeilinger were awarded the Nobel prize “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science” [1]. In this article, we want to put the Nobel Prize in perspective, and replace the three laureates’ contribution in their historical context.
