Forskare från Kyoto universitet och Hiroshima universitet har skapat en ny teknik för att identifiera W-tillstånd, en komplex form av kvantsammanflätning. Framsteget kan stödja utvecklingen inom kvantdatorer och kommunikation.

Ett team lett av Shigeki Takeuchi demonstrerade metoden med hjälp av tre fotoner i en stabil optisk krets. Enheten utför en kvant-Fourier-transform baserad på den cykliska skiftsymmetrin hos W-tillstånd. Den skiljer mellan olika W-tillstånd med tre fotoner i en enda mätning utan att behöva omfattande justeringar under drift.
