The Consistency of Quantum Mechanics Implies its Non-Determinism

TL;DR

This paper demonstrates that assuming the logical consistency of quantum mechanics inherently leads to its non-deterministic nature, independent of observer free will, thus linking consistency to indeterminism.

Contribution

It shows that the non-determinism of quantum mechanics can be derived solely from its logical consistency, removing the need for assumptions about observer free will.

Findings

Logical consistency implies non-determinism in QM

Observer free will is not necessary for quantum indeterminism

Quantum mechanics' non-contradiction leads to inherent randomness

Abstract

In a previous paper (arXiv:1008.3661v1[quant-ph] 21 Aug 2010), we have given a purely logical proof of the Conway and Kochen Free Will theorem in QM: the freedom of the observer implies the freedom of the observed particle. Here we show that the hypothesis of the observer's freedom is not necessary: the assumption of the (informal) consistency (non contradiction) of QM implies its non-determinism relative to physical events (the freedom of observed particles).
