Comment on "Observing the Average Trajectories of Single Photons in a Two-Slit Interferometer"

TL;DR

This paper critically examines previous claims about photon trajectories in a two-slit experiment, reanalyzes data, and concludes that the average photon trajectories align with Bohmian mechanics, clarifying their behavior and interpretation.

Contribution

It provides a detailed reanalysis of earlier experimental data, confirming the agreement of average photon trajectories with Bohmian trajectories and discussing their implications.

Findings

Average photon trajectories agree with Bohmian trajectories

Reanalysis confirms trajectories do not converge to high probability regions

Discussion of interpretations of photon trajectory behavior

Abstract

Kocsis et al. (Science, Reports 3 June 2011, p. 1170) state that the experimentally deduced average photon trajectories are identical to the particle trajectories of Bohm's quantum mechanics. No supporting evidence, however, was provided. The photon trajectories presented in their report do not converge to high probability regions, a familiar and necessary behavior of Bohm trajectories. We reanalyze their data and calculations, conclude that the average photon trajectories do indeed agree with Bohm, and discuss possible interpretations of this result.
