论文摘要
我们调查了纯净的爱因斯坦 - 波多尔斯基 - 罗森 - 罗森 - 在大规模颗粒自由度的内部程度中如何受到弯曲的时空背景的影响。我们考虑了对爱因斯坦 - 希尔伯特作用的校正在曲率不变的模型，我们专注于弱场极限。我们通过违反clauser-horne-hold-holt-holt不平等的方式来量化非内地量子相关性，并显示弯曲的背景如何抑制由于对爱因斯坦重力的纠正而导致的一般相对性和进一步的贡献。我们的结果可以推广到无质量的颗粒，例如光子对，因此可以适当利用以设计扩展重力模型的精确实验测试。
We investigate how pure-state Einstein-Podolsky-Rosen correlations in the internal degrees of freedom of massive particles are affected by a curved spacetime background described by extended theories of gravity. We consider models for which the corrections to the Einstein-Hilbert action are quadratic in the curvature invariants and we focus on the weak-field limit. We quantify nonlocal quantum correlations by means of the violation of the Clauser-Horne-Shimony-Holt inequality, and show how a curved background suppresses the violation by a leading term due to general relativity and a further contribution due to the corrections to Einstein gravity. Our results can be generalized to massless particles such as photon pairs and can thus be suitably exploited to devise precise experimental tests of extended models of gravity.
