Description
It has been suggested that space-time geometries can emerge from quantum entanglement in the context of AdS/CFT and beyond. Inspired by travel-time tomography in seismology, we construct a geometry detector that quantitatively determines whether classical space-times can actually emerge from certain entanglement patterns. Then we explicitly reconstruct the best-fit emergent holographic geometries from various entanglement data extracted from a 1-dimensional quantum system, such as a quantum spin chain at criticality, for both static and dynamical cases. Finally, we discuss how this approach may be used for understanding simulated classical/quantum gravitational dynamics in a laboratory setting.
