Comment on Afshar's expriments

Abstract

Results of the experiments carried out in [Shahriar S. Afshar, Proc. SPIE bf 5866 (2005) 229-244] and [Shahriar S. Afshar, AIP Cof. Proc. 810, (2006) 294-299] are reviewed and their interpretation by the authors is questioned. Arguments are supported by numerical simulations.

Complementarity and the Afshar Experiment

Tabish Qureshi

A modified two-slit interference experiment, proposed and carried out by Shahriar Afshar [first reported by M. Chown, New Scientist {\\bf 183}, 30 (2004)], claims to demonstrate a violation of Bohr's complementarity principle. We point out the flaw in Afshar's analysis and show why complementarity is robust and cannot be violated in any experiment which is a variant of the conventional two-slit experiment.

Complementarity and Afshar's experiment

Aurélien Drezet

In this article we criticize the experiment realized by S. Afshar [Proc. SPIE 5866, 229-244 (July 2005)]. We analyze Bohr's complementarity and show that the interpretation proposed by Afshar is misleading.

The Afshar Two-Slit Experiment and Complementarity

Ruth E. Kastner

A modified version of Young's experiment by Shahriar Afshar demonstrates that, prior to a ``which-way'' measurement indicating which slit a particle goes through, an interference pattern exists. It has been claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer's Transactional Interpretation accomodates the result. It is shown that the Afshar experiment is isomorphic in key respects to a a spin one-half particle prepared as ``spin up along x'' and post-selected in a specific state of spin along z. It is concluded that Bohr would have had no more problem accounting for the Afshar result than he would in accounting for the aforementioned pre- and post-selection spin experiment, in which the particle's preparation state is confirmed by a nondestructive measurement prior to post-selection.
