Dans la premi\u00e8rere exp\u00e9rience, des photons composant un rayon de lumi\u00e8re en forme d\u2019anneau \u00e9taient coup\u00e9s en deux et certains des photons semblaient agir comme des particules alors que d\u2019autres interf\u00e9raient avec d\u2019autres photons \u00e0 la mani\u00e8re d\u2019une onde.<\/span><\/p>\n

Toutefois, les auteurs de ce nouvel article montrent que les photons agissent d\u00e9pendamment de leur position dans le rayon, et n\u2019agissent donc pas en m\u00eame temps comme une particule et comme une onde. La premi\u00e8re exp\u00e9rience n\u2019\u00e9tait donc qu\u2019une erreur d\u2019\u00e9chantillonnage.<\/span><\/p>\n
