Paradox or non-paradox in wave-particle duality

TL;DR

This paper critically examines the Afshar experiment, arguing that it does not threaten Bohr's principle of complementarity despite claims to the contrary.

Contribution

It provides a detailed analysis showing that the Afshar experiment does not refute the principle of complementarity, clarifying the experiment's implications.

Findings

The Afshar experiment does not violate Bohr's complementarity.

Bohr's principle remains valid despite the experiment.

The analysis clarifies the interpretation of wave-particle duality.

Abstract

We analyze the experiment recently realized by S. Afshar et al. [1] in order to refute the principle of complementarity. We discuss the general meaning of this principle and show that contrarily to the claim of the authors Bohr's complementarity is not in danger in this experiment.
