论文摘要
我们说明了全息图随机张量网络玩具模型的批量重建思想。具体而言，我们演示了PETZ重建图如何通过利用复制品技巧来从边界数据中获取批量操作员。我们还借此机会评论了粗粒和随机预测之间的差异。
We illustrate the ideas of bulk reconstruction in the context of random tensor network toy models of holography. Specifically, we demonstrate how the Petz reconstruction map works to obtain bulk operators from the boundary data by exploiting the replica trick. We also take the opportunity to comment on the differences between coarse-graining and random projections.
