Des chercheurs de l'Université de Kyoto et de l'Université d'Hiroshima ont créé une nouvelle technique pour identifier les états W, une forme complexe d'intrication quantique. Cette avancée pourrait soutenir les progrès de l'informatique et de la communication quantiques.

Une équipe dirigée par Shigeki Takeuchi a démontré cette méthode en utilisant trois photons dans un circuit optique stable. Le dispositif effectue une transformation de Fourier quantique basée sur la symétrie de décalage cyclique des états W. Il permet de distinguer différents états W à trois photons lors d'une mesure unique, sans nécessiter d'ajustements extensifs durant son fonctionnement.
