The double-slit quantum eraser experiments and Hardy's paradox in the quantum linguistic interpretation

TL;DR

This paper reformulates key quantum experiments and paradoxes within the linguistic interpretation of quantum mechanics, emphasizing a shift from physical realism to a language-based worldview.

Contribution

It develops a linguistic interpretation framework for quantum phenomena, positioning it as the final version of the Copenhagen interpretation and highlighting its philosophical implications.

Findings

Reformulation of double-slit and quantum eraser experiments in linguistic terms

Analysis of Hardy's paradox within the linguistic interpretation

Assertion that the Copenhagen interpretation is fundamentally a linguistic worldview

Abstract

Recently we proposed the linguistic interpretation of quantum mechanics (called quantum and classical measurement theory), which was characterized as a kind of metaphysical and linguistic turn of the Copenhagen interpretation. This turn from physics to language does not only extend quantum theory to classical systems but also yield the quantum mechanical world view (i.e., quantum philosophy or quantum language). The purpose of this paper is to formulate the double-slit experiment, the quantum eraser experiment, Wheeler's delayed choice experiment, Hardy's paradox and the three boxes paradox (the weak value associated with a weak measurement due to Aharonov, et al.) in the linguistic interpretation of quantum mechanics. Through these arguments, we assert that the linguistic interpretation is just the final version of so called Copenhagen interpretation. And therefore, we conclude that the Copenhagen interpretation does not belong to physics (i.e., the realistic world view) but the linguistic world view.
