Bulk Reconstruction

This thesis studies bulk reconstruction, especially its connection with quantum entanglement. Bulk reconstruction, by the name, is to reconstruct the bulk gravitational theory from boundary conformal field theory in holography. In the end, people want to fully understand how the higher dimensional gravitational theory appears from some quantum field theory and then to understand the quantum gravity theory.

In the first part of this thesis, we review the basic aspects, including AdS/CFT and holographic entanglement entropy. Then we review the reconstruction of bulk fields on the classical background, or in quantum error correction language, inside the code subspace. In the final part, we study the reconstruction of geometry, including dynamics and the metric itself, and we also explore the possibility of the reconstruction of the compact space.
