我们测量了钙原子辐射级联中发射光子的线性偏振相关。高效源提供了改进的统计准确性和执行新测试的能力。我们的结果与量子力学的预言非常吻合，强烈地违反了广义Bell不等式，并排除了整个现实局域理论。当光源-偏振器间距达到6.5 m时，观察到的结果无显著变化。
We have measured the linear polarization correlation of the photons emitted in a radiative atomic cascade of calcium. A high-efficiency source provided an improved statistical accuracy and an ability to perform new tests. Our results, in excellent agreement with the quantum mechanical predictions, strongly violate the generalized Bell's inequalities, and rule out the whole class of realistic local theories. No significant change in results was observed with source-polarizer separations of up to 6.5 m.
