초록/해제  
요약The black hole information paradox and recent progress on its resolution have been driven by the influx of ideas from quantum information and quantum error correction applied to the Anti-de Sitter/Conformal Field Theory (AdS/CFT) duality. Currently, AdS/CFT is one of the leading theories for making progress on the longstanding quest to understand quantum gravity. In this dissertation, we strengthen the connection in the opposite direction, making progress in quantum information inspired by insights from AdS/CFT.The traversable wormhole protocol was initially discovered in the context of two-sided black holes, yet appears to be a teleportation protocol for chaotic quantum systems. We discuss preparation of the thermofield double, a key resource in this, as well as a demonstration of this protocol in quantum hardware.We extend proof techniques for entropy inequalities obeyed by holographic states. Famously, the set of quantum entropy inequalities for greater than four parties is not fully characterized. However, we report on progress on placing structure to the entropies of quantum states generated by a minimal cut prescription for hypergraphs and topological links, generalizing away from the graph states that reproduce holographic entropies.In the final section of this dissertation, we demonstrate a powerful framework for building new quantum error correcting codes inspired by the connection between tensor networks and quantum error correction in quantum gravity. Using machine learning techniques to build new codes for tailored desiderata, we showcase novel codes that outperform state of the art codes at various tasks.
