论文摘要
我们表明，页面时间后，蒸发黑洞的规范纯化由两个渐近边界之间的短，连接的洛伦兹虫洞组成，其中一个与辐射单位相关。这提供了对页面时间后蒸发黑洞的ER = EPR预测的定量和一般实现。这进一步给出了辐射熵的标准ADS/CFT计算（同源性约束而没有修改）。在页面时间之前，规范纯化由两个断开的半经典黑洞组成。由此，我们构造了两个纠缠的双方纠缠式CFT状态，具有相等（且大）的纠缠状态，其中一个半经典双重偶具有连接的ERB，而另一个则没有。在此示例中，我们推测多部分纠缠的度量可能会在时空的出现中提供更完整的图片。
We show that the canonical purification of an evaporating black hole after the Page time consists of a short, connected, Lorentzian wormhole between two asymptotic boundaries, one of which is unitarily related to the radiation. This provides a quantitative and general realization of the predictions of ER=EPR in an evaporating black hole after the Page time; this further gives a standard AdS/CFT calculation of the entropy of the radiation (without modifications of the homology constraint). Before the Page time, the canonical purification consists of two disconnected, semiclassical black holes. From this, we construct two bipartite entangled holographic CFT states, with equal (and large) amount of entanglement, where the semiclassical dual of one has a connected ERB and the other does not. From this example, we speculate that measures of multipartite entanglement may offer a more complete picture into the emergence of spacetime.
