Comment on “Biphoton double-slit experiment”

Abstract

In a recent paper [Phys. Rev. A 68, 033803 (2003)] experimental results on a double-slit configuration with two entangled bosons are presented. The authors argue that their data contradicts the de Broglie--Bohm interpretation of quantum mechanics. In this Comment we show that this conclusion is incorrect.

Reply to Comment on Experimental realization of a first test of de Broglie–Bohm theory

We reply to Akhavan and Golshani's comment on our double-slit experiment addressed to test standard quantum mechanics versus de Broglie–Bohm theory. We show that their results, albeit representing a relevant contribution to the discussion on the realizability of a test of de Broglie–Bohm theory, do not allow us to draw any conclusion about our experiment since their wavefunction does not describe well the photon states produced by our set-up. On the other hand, we give arguments of why our experiment can be considered a good realization of the theoretical proposal of Ghose (1999 Foundations of Quantum Theory and Quantum Optics ed S M Roy), Ghose et al (2001 Phys. Lett. A 290 205) and Golshani and Akhavan ( 2001 J. Phys. A: Math. Gen. 34 5259 ).

Biphoton double-slit experiment

G. Brida, E. Cagliero, Giuseppe Falzetta +3 more

In this paper we present a double-slit experiment where two indistinguishable photons produced by type-I parametric down-conversion are each sent to a well-defined slit. Data about the diffraction and interference patterns for coincidences are presented and discussed. An analysis of these data allows a test of standard quantum mechanics against the de Broglie--Bohm theory.

An innovative biphoton double slit experiment

G. Brida, E. Cagliero, Marco Genovese +4 more

We report on a double slit experiment where indistinguishable correlated photons generated through spontaneous parametric down-conversion, are each sent to a well-defined slit. An analysis of the results allows a test of de Broglie-Bohm mechanics against standard quantum mechanics.

Comment on Experimental realization of a first test of de Broglie–Bohm theory

Omid Akhavan, Mehdi Golshani

In a recent paper, Brida et al (2002 J. Phys. B: At. Mol. Opt. Phys. 35 4751) reported the first experimental realization for testing of de Broglie–Bohm (dBB) theory against standard quantum mechanics (SQM), based on a suggested scheme presented in Golshani and Akhavan (2001 J. Phys. A: Math. Gen. 34 5259). However, some details of their experiment are not compatible with our suggestion. Therefore, their conclusion, in which the experimental data are in complete agreement with SQM but show some deviations from dBB predictions, cannot be considered as a final verdict.

Double Slit to Cross Double Slit to Comprehensive Double Slit Experiments

Huei Peng

Abstract Young’s double slit experiments, which represent the mystery of quantum mechanics, have been interpreted by quantum probability waves and de Broglie-Bohm’s trajectory/pilot waves. To study in detail, the double slit experiments are extended to the cross double slit experiments. We argue that an interpretation must be able to explain all of the double slit and cross double slit experiments consistently. To test the interpretations, the comprehensive double slit experiments have been performed, which challenge both the wave interpretation and the trajectory interpretation. The cross double slit experiments and comprehensive double slit experiments provide a new tool for studying the mystery of double slit, wave-particle duality, complementarity principle, wave theory and trajectory theory. In this article, we review the cross double slit experiments and comprehensive double slit experiments, and report new experiments.
