Abstract

We address the question of whether the quantum-mechanical wave function Ψ of a system is uniquely determined by any complete description Λ of the system's physical state. We show that this is the case if the latter satisfies a notion of "free choice". This notion requires that certain experimental parameters---those that according to quantum theory can be chosen independently of other variables---retain this property in the presence of Λ. An implication of this result is that, among all possible descriptions Λ of a system's state compatible with free choice, the wave function Ψ is as objective as Λ.

Why This Paper Matters
