Researchers at Northeastern University and Brookhaven National Laboratory have mathematically derived the maximum distance for combinatorial holographic quantum secret sharing schemes, establishing precise limits on how logical information can be encoded across boundary subregions. By leveraging AdS3/CFT2 correspondence, this work identifies distinct phase transition points in multipartite entanglement wedges that define the performance thresholds of both perfect and non-threshold varieties. These findings advance fundamental understanding of quantum error correction mechanisms by linking gravitational geometry to robust data security protocols against erasures.

Researchers from Northeastern University and Brookhaven National Laboratory explored holographic quantum secret sharing, deriving the maximum distance for encoding & protecting information.

Researchers at Northeastern University and Brookhaven National Laboratory have derived the maximum distance within novel combinatorial holographic quantum secret sharing (CHQSS) schemes, characterizing how logical information of a bulk subregion can be encoded in the boundary and protected from erasures of boundary subregions. This work leverages the connection between gravity, as described by Anti-de Sitter space (AdS3), and quantum information theory via Conformal Field Theory (CFT2), utilizing the AdS3/CFT2 correspondence as its framework. The study identifies multiple distinct phase…
