Quantum indeterminacy: a matter of degree?

摘要

The degreed view is an influential account in the debate on quantum value indefiniteness, linking the gradedness of quantum properties to quantum indeterminacy. This paper challenges the connection between degrees and indeterminacy by presenting an example of a graded quantum property that does not entail metaphysical indeterminacy. Through an investigation of two graded approaches to location in quantum mechanics, the paper argues that while the first account, degreed instantiation of exact location, is indeterminate, the second account, degreed quantum location, is not. This indicates that indeterminacy and degrees are not inherently linked, offering a novel perspective on quantum ontology. The paper advocates adopting a graded view of quantum properties without indeterminacy, potentially leading to a paradigm shift in understanding quantum phenomena.
