A realistic interpretation of quantum mechanics. Asymmetric random walks in a discrete spacetime

TL;DR

This paper proposes a realistic interpretation of quantum mechanics where particles follow definite, probabilistic paths in a discrete spacetime, aligning with standard quantum predictions for large ensembles.

Contribution

It introduces a novel interpretation of quantum mechanics based on asymmetric random walks in a discrete spacetime, linking particle paths to macroscopic properties.

Findings

Predictions match standard quantum mechanics for large ensembles.

Particles follow non-deterministic paths influenced by their properties.

Spacetime discretization is essential for the interpretation.

Abstract

In this paper, I propose a realistic interpretation (RI) of quantum mechanics, that is, an interpretation according to which a particle follows a definite path in spacetime. The path is not deterministic but it is rather a random walk. However, the probability of each step of the walk is found to depend from some average properties of the particle that can be interpreted as its propensity to have a certain macroscopic momentum and energy. The proposed interpretation requires spacetime to be discrete. Prediction of standard quantum mechanics coincide with predictions of large ensembles of particles in the RI.
