测量了钙辐射级联中发射的光子对的线偏振关联。新的实验方案使用双通道偏振器(即Stern-Gerlach滤光片的光学模拟)，是对Einstein-Podolsky-Rosen-Bohm Gedanken实验的直接变换。目前的结果与量子力学的预测非常一致，导致了有史以来最大的违反广义贝尔不等式的行为。
The linear-polarization correlation of pairs of photons emitted in a radiative cascade of calcium has been measured. The new experimental scheme, using two-channel polarizers (ie, optical analogs of Stern-Gerlach filters), is a straightforward transposition of Einstein-Podolsky-Rosen-Bohm gedankenexperiment. The present results, in excellent agreement with the quantum mechanical predictions, lead to the greatest violation of generalized Bell's inequalities ever achieved.
