Physical reality in asymmetrical double-slit experiments

Abstract

The recent state-of-the-art double-slit experiments with single electrons and single photons seem to emphasize contradictable dilemma concerning the ontological physical reality in quantum physics. Because of the importance of this problem, we propose and perform another modified laser-beam asymmetrical double-slit experiment. In the results, a Feynman condition with closing mask allows to assess qualitatively the interference contributions of photons passing through one or another slit. Moreover, a definite "which-way" phenomenon has been identified with a high experimental confidence. This would be the simplest way without any disturbance of the photon beam to observe simultaneously both their path and momentum in consistency with the quantum statistical concept.

A possible solution to the which-way problem by asymmetrical double-slit experiments

“…The plan of this article is organized as follows: In section 2 a 'which-way' asymmetrical double-slit methodology with a laser beam is described; in section 3 the main experimental samples are presented; in section 4 the obtained experimental data are reviewed for discussion and interpretation. Some data that support this study are openly available at [25].…”
