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

摘要

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