非局域關聯存在已經被實驗間接證明
Bell 不等式的違背是量子非局域關聯存在的重要證據之一。下面這篇報道說“Bell 不等式的違背”已經被實驗證實。

Violation of Bell's Inequality under Strict Einstein Locality Conditions
We observe strong violation of Bell's inequality in an Einstein-Podolsky-Rosen-type experiment with independent observers. Our experiment definitely implements the ideas behind the well-known work by Aspect et al. We for the first time fully enforce the condition of locality, a central assumption in the derivation of Bell's theorem. The necessary spacelike separation of the observations is achieved by sufficient physical distance between the measurement stations, by ultrafast and random setting of the analyzers, and by completely independent data registration.
據說這是一篇諾貝爾提名獎研究工作。
