Fig. 1: Complementary recovery in holography.
a In continuum AdS/CFT on slices at constant time t, a bipartition of the boundary CFT into two regions A and Ac is equivalent to a bipartition of the bulk into two entanglement wedges a and ac, separated by a Ryu–Takayanagi surface γA. Any bulk (field) operator ϕ(x) can be fully reconstructed on either A or Ac, but not both. b In the holographic tensor network code introduced here, a boundary bipartition leads to bulk wedges that are separated by a large residual region (white); an operator ϕ in this region cannot generally be reconstructed on either A and Ac.
