Every PPT channel has finite entanglement breaking index
Sang-Jun Park
We prove that every PPT linear map has finite entanglement breaking index, thereby establishing the eventual entanglement breaking property of PPT channels in full generality. Furt…

A solution to 2-copy distillability of Werner states
Jinshi Fu, Li Gao, Sang-Jun Park
Entanglement distillation is a fundamental task in quantum information theory. In this work, we prove that Werner states in arbitrary dimension are 2-copy distillable if and only i…
