Minimal Set of Quantum Postulates and Realistic Interpretation of Quantum Mechanics
Sumio Wada

TL;DR
This paper proposes a simplified interpretation of quantum mechanics that eliminates controversial postulates by relying on the wave function, decoherence, and relative frequency, providing a more realistic understanding of quantum phenomena.
Contribution
It introduces a minimal set of postulates for quantum mechanics and offers a realistic interpretation that avoids wave function collapse and quantum probability rule.
Findings
Wave function suffices as a representation of quantum states
Decoherence explains the emergence of classicality
Relative frequency accounts for quantum probabilities
Abstract
We argue that quantum mechanics makes sense without such controversial postulates as the wave function collapse, the quantum probability rule and the observable postulate. We only need the existence of a wave function as a representation of a state, its dynamical evolution rule and another rather trivial postulate proposed here (Read-Off Postulate). The wave function collapse and the probability rule are replaced with intrinsic properties of the theory, i.e. decoherence and relative frequency, respectively. Interpretation of the wave function as a faithful representation of the reality naturally emerges, although quantum reality has a peculiar feature which distinguishes it from classical reality.
