Researchers Approximate Data Retrieval from Multiple Connected Universes Using Three Boundaries

Constructing cosmological states beyond dual boundaries was previously impossible. Now, calculations extend these constructions to encompass three or more holographic conformal field theories, enabling recovery of quantum information, specifically, a code of dimension K, with negligible errors when K/b approaches zero. This advancement offers new routes for modelling universes and exploring potential quantum error correction within them.
