P Hayden, G Penington - Journal of High Energy Physics, 2019 - Springer
A bstract When the bulk geometry in AdS/CFT contains a black hole, boundary subregions
may be sufficient to reconstruct certain bulk operators if and only if the black hole microstate …

Quantum minimal surfaces from quantum error correction
