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…
Quantum Broadcast Channel Simulation via Multipartite Convex Splitting
Hao-Chung Cheng, Li Gao, Mario Berta
We show that the communication cost of quantum broadcast channel simulation under free entanglement assistance between the sender and the receivers is asymptotically characterized…
Tight One-Shot Analysis for Convex Splitting with Applications in Quantum Information Theory
Hao-Chung Cheng, Li Gao
Convex splitting is a powerful technique in quantum information theory used in proving the achievability of numerous information-processing protocols such as quantum state redistri…
Sufficient statistic and recoverability via Quantum Fisher Information metrics
Li Gao, Haojian Li, Iman Marvian +1
We prove that for a large class of quantum Fisher information, a quantum channel is sufficient for a family of quantum states, i.e., the input states can be recovered from the outp…
