Scientists observe stronger-than-binary correlations with entangled photonic qutrits

(University of Science and Technology of China) Professor LI Chuanfeng's Group of CAS Key Laboratory of Quantum Information demonstrates the existence of stronger-than-binary correlations in quantum mechanics for the first time. The results are published in Physical Review Letters on May 4 and incorporated into the 'Editor's Suggestion.' Li Chuanfeng, Liu Biheng, and others collaborated with theoretical physicists from Spain, Hungary, and Germany all contributes to the achievement.
