摘　　要：分析了量子力学中的空间关联与通讯的关系与差别 ,提出了统计可分隔性概念 ,由此证明了超光速量子通讯不可能 .We analyse the relation and the difference between the quantum correlation of two points in space and the communication between them. The statistical separability of two points in the space is defined and proven. From this statistical separability, we prove that the superluminal quantum communication betwcen different points is impossible. To emphasis the compatibility between the quantum theory and the relativity, we write the von Neumann equation of density operator evolution in the multi-time form.
