Scanning Tunneling Macroscopy, Black Holes, and AdS/CFT Bulk Locality

Understand

We establish resolution bounds on reconstructing a bulk field from boundary data on a timelike hypersurface.

  • If the bulk only supports propagating modes, reconstruction is complete.
  • If the bulk also supports evanescent modes, local reconstruction is not achievable unless one has exponential precision in knowledge of the boundary data.
  • Without exponential precision, for a Minkowski bulk, one can reconstruct a spatially coarse-grained bulk field, but only out to a depth set by the coarse-graining scale.
