# Entanglement wedge cross-section The entanglement wedge cross-section is a quantity defined in the bulk. There are several proposals for its boundary dual. ## CFT dual - [[0258 Entanglement of purification]]? - hard because it involves minimisation - [[0166 Reflected entropy]] - [[2019#Dutta, Faulkner]] - [[0392 Differential purification]] - [[EspindolaGuijosaPedraza2018]] - entanglement [[0265 Distillation]] - [[AgonDeBoerPedraza2018]][](https://arxiv.org/abs/1811.08879) - [[LevinDeWolfeSmoth2019]][](https://arxiv.org/abs/1909.04727) - balanced partial entanglement - [[Wen2021]][](https://arxiv.org/abs/2103.00415), [[Wen2018]], [[Wen2019]]
