Para peneliti dari Kyoto University dan Hiroshima University telah menciptakan teknik baru untuk mengidentifikasi status W, sebuah bentuk kompleks dari keterikatan kuantum. Kemajuan ini dapat mendukung perkembangan komputasi dan komunikasi kuantum.

Tim yang dipimpin oleh Shigeki Takeuchi mendemonstrasikan metode tersebut menggunakan tiga foton dalam sirkuit optik yang stabil. Perangkat ini melakukan transformasi Fourier kuantum berdasarkan simetri pergeseran siklik dari status W. Alat ini membedakan berbagai status W tiga foton dalam satu pengukuran tanpa memerlukan penyesuaian yang rumit selama pengoperasian.
