Geometrizing the partial entanglement entropy: from PEE threads to bit threads

J Lin, Y Lu, Q Wen - Journal of High Energy Physics, 2024 - Springer
A bstract We give a scheme to geometrize the partial entanglement entropy (PEE) for
holographic CFT in the context of AdS/CFT. More explicitly, given a point x we geometrize …

Distilled density matrices of holographic partial entanglement entropy from thread-state correspondence

YY Lin - Physical Review D, 2023 - APS
Within the framework of holographic duality, conditional mutual information (CMI) is often
understood as a correlation between “region pairs” and is closely related to the concept of …
