标题： EPR effect in gravitational field: nature of non-locality

摘要： 通过单个标量粒子衰变产生的两个粒子自旋投影的相关性来实现爱因斯坦-波多尔斯基-罗森效应的情况，在粒子在引力场中传播的情况下被考虑。 空间方向的全局定义的缺失使得不清楚在这种情况下相关性是否存在，如果存在的话，远距离区域中的哪些方向必须相关。 显示在引力场中可能存在近似的相关性，相关方向通过粒子世界线上的平行传输相互连接。 这是因为量子非局域性的实际起源建立在局部过程中。 显示英文摘要

摘要： The realization of the Einstein-Podolsky-Rosen effect by the correlation of spin projections of two particles created in the decay of a single scalar particle is considered for particles propagating in gravitational field. The absence of a global definition of spatial directions makes it unclear whether the correlation may exist in this case and, if yes, what directions in distant regions must be correlated. It is shown that in a gravitational field an approximate correlation may exist and the correlated directions are connected with each other by the parallel transport along the world lines of the particles. The reason for this is that the actual origin of the quantum non-locality is founded in local processes.
