On idealism of Anton Zeilinger's information interpretation of quantum mechanics

TL;DR

This paper critiques Zeilinger's information interpretation of quantum mechanics, arguing it is rooted in idealism and advocating for a more realistic, contextual approach based on the impossibility of discussing quantum properties independently of measurement context.

Contribution

It challenges Zeilinger's foundational principle, proposing a shift from idealism to a realistic, contextual understanding of quantum systems.

Findings

Zeilinger's principle is identified as an idealistic stance.

Quantum properties depend on the measurement context.

A move towards a realistic principle of contextuality is proposed.

Abstract

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.
