Modified Afshar Experiment: Calculations

TL;DR

This paper presents calculations for a modified Afshar experiment, showing that the level of which-way information and visibility is higher than previously estimated, aligning with experimental results and challenging traditional interpretations.

Contribution

It provides a simplified calculation approach for the Afshar experiment, confirming experimental findings and refining the understanding of wave-particle duality.

Findings

Numerical results agree with experimental data.

Higher than estimated which-way information and visibility.

Supports challenges to Bohr's Principle of Complementarity.

Abstract

The Afshar experiment is a relatively simple two-slit experiment with results that appear to show a discrepancy with the predictions of Bohr's Principle of Complementarity. We report on the results of a calculation using a simpler but equivalent set-up called the modified Afshar experiment. Numerical results are in agreement with the experimental results performed on the Afshar experiment set-up. Calculations show that the level of which-way information and visibility in the Afshar experiement is higher than originally estimated.
