Although, quantum theory ( from nonrelative quantum mechanics to relative quantum field theories) describes the world in terms of locality, like the classic theory. But as far as its essence concerned, quantum theory is still a space nonlocal theory in terms of locality. 尽管和经典理论一样,量子理论(从非相对论量子力学到相对论量子场论)采用了局域描述的方法,但就本质而言,量子理论依然是在局域描述外衣下的空间非局域理论。
