Entanglement negativity and minimal entanglement wedge cross sections in holographic theories

J Kudler-Flam, S Ryu - Physical Review D, 2019 - APS
We calculate logarithmic negativity, a quantum entanglement measure for mixed quantum
states, in quantum error-correcting codes and find it to equal the minimal cross sectional …

Leading order corrections to the quantum extremal surface prescription

C Akers, G Penington - Journal of High Energy Physics, 2021 - Springer
A bstract We show that a naïve application of the quantum extremal surface (QES)
prescription can lead to paradoxical results and must be corrected at leading order. The …
