Optimal Second-Order Rates for Quantum Information Decoupling
Yu-Chen Shen, Li Gao, Hao-Chung Cheng
In this paper, we consider the standard quantum information decoupling, in which Alice aims to decouple her system from the environment by local operations and discarding some of h…

Privacy Amplification Against Quantum Side Information Via Regular Random Binning
Yu-Chen Shen, Li Gao, Hao-Chung Cheng
We consider privacy amplification against quantum side information by using regular random binning as an effective extractor. For constant-type sources, we obtain error exponent an…
