Finite-Blocklength and Exponential Analyses for Universal Entanglement and Coherence Distillation under Various Free Operations

Zhiwen Lin, Ke Li, Kun Fang

Historically, entanglement and coherence distillation focused on the distillable rate under full knowledge of the initial state. In this paper, we develop a unified finite-blocklen…

Adversarial quantum channel discrimination

Kun Fang, Hamza Fawzi, Omar Fawzi

We introduce a new framework for quantum channel discrimination in an adversarial setting, where the tester plays against an adversary. We show that in asymmetric hypothesis testin…

Generalized quantum asymptotic equipartition

Kun Fang, Hamza Fawzi, Omar Fawzi

The asymptotic equipartition property (AEP) states that in the limit of a large number of independent and identically distributed (i.i.d.) random experiments, the output sequence i…
