DESCRIPTION:Over the past decade\, perspectives from quantum i
 nformation have shed valuable insight into the con
 jectured anti-de Sitter space/conformal field theo
 ry (AdS/CFT) correspondence in high-energy physics
 . In particular\, a growing body of evidence sugge
 sts that (approximate) quantum error correction co
 uld be a mechanism underlying the holographic corr
 espondence: local bulk AdS observables are encoded
  as operator algebraic quantum error correcting co
 des on a subspace of the boundary CFT Hilbert spac
 e and bulk AdS locality emerges from complementary
  recovery of the encoding boundary algebras. Motiv
 ated by this theory and a recent conjecture of Bou
 sso et. al. on the bulk AdS description of boundar
 y cocycle flow\, we characterize (approximate) com
 plementary recovery in terms of (approximate) inte
 rtwining of bulk and boundary cocycle derivatives.
  Using a recent framework of Dybalski-Wrochna\, we
  then show that the aforementioned complementary r
 ecovery holds for Weyl algebras of Klein-Gordon fi
 elds in AdS wedges\, yielding an operator algebrai
 c version of subregion-subregion duality. Based on
  joint work with Monica Jinwoo Kang.\n&nbsp\;
