量子时空中的面积量子

Area quantum in quantized space-time

用不同于其他文献的方法推导出量子化空间中面积谱为16πh-A(j),用该面积谱以便于推算出黑洞的熵.利用最小面积量子值为1/2探讨qubit的来源,同时对空间存在的EPR纠缠态、纠缠态的非定域性,以及面积量子具有的关联变更给出论证.

In loop gravity by considering the two types of grasping actions on the segments through an edge of spin network, an area spectrum being is got, by using this spectrum the entropy of black hole is calculated. Employing the area quantum, we demonstrated a possible origin of qubit, and gave some arguments about existences of the EPR entanglement, the non-local property of entangled state, as well as the relevancy change of area quantum states in quantized space.
