Two Slits Interference Is Compatible with Particles' Trajectories

TL;DR

This paper presents a numerical experiment demonstrating that two-slit interference can be compatible with particles having definite trajectories, supporting a contextual interpretation of quantum probabilities.

Contribution

It introduces a simple numerical model showing that interference patterns do not exclude particles having known trajectories, challenging common interpretations.

Findings

Interference patterns can coexist with particle trajectories.

The model supports a contextual interpretation of quantum mechanics.

Particles' paths can be consistent with observed interference.

Abstract

We propose a simple numerical experiment of two slits interference of particles. It disproves the popular belief that such an interference is incompatible with a knowledge which slit each particle came through or, more generally, ``quantum particles could not have trajectories''. Our model is an illustration to the contextual interpretation of quantum probabilities.
