A conclusive experiment on wave-particle duality of light ?

摘要

We report the results of a new realization of Ghose, Home and Agarwal experiment to test wave-particle duality where some limitations of the former experiment, realized by Mizobuchi and Othake, are overcome. Our results, in agreement with quantum mechanics predictions, indicates that complementarity between wave and particle behavior must be interpreted in a weaker sense as a gradual disappearing of interference when "which-path" indications are obtained and not as a mutual exclusive aspects as in the original Bohr's statement.
