Quantum mechanics as a macrorealistic theory

TL;DR

This paper argues that quantum mechanics aligns with macrorealism principles, challenging the notions of nonlocality and Bell's theorem, and presents a macrorealistic model for one-dimensional scattering involving Cat states.

Contribution

It introduces a macrorealistic interpretation of quantum mechanics that reconciles superposition with macrorealism, disputing the nonlocality implied by Bell's theorem.

Findings

Quantum mechanics respects macrorealism principles.

Bell's theorem and nonlocality claims are based on invalid assumptions.

A macrorealistic model for one-dimensional scattering is proposed.

Abstract

As contrasted with physicists to idolize Bell's theorem and quantum nonlocality, we argue that quantum mechanics (QM), in reality, respects the principles of a macroscopic realism (PMRs). The current QM to tell us that "... the state of a system can be instantaneously changed by a distant measurement >..." cannot be treated as a physical theory. Its key statements - that the EPR-Bell experiments to violate Bell's inequality verify nonlocality, and nonlocal correlations respect special relativity - are false. Both the EPR-Bell experiments and theorems to support the "non-signalling principle" are based on the implicit assumption that all quantum postulates and, in particular, Born's averaging rule are fully applicable to Cat states. However, this is not the case. Introducing observables (e.g., correlations) for Cat states violates the correspondence principle. Pure (macro- and micro-)Cat states must be governed both by the PMRs and superposition principle. Our (macrorealistic) model of a one-dimensional completed scattering shows how these principles coexist with each other, in the case of a one-electron micro-Cat state.
