Resolvability of classical-quantum channels
Masahito Hayashi, Hao-Chung Cheng, Li Gao
Channel resolvability concerns the minimum resolution for approximating the channel output. We study the resolvability of classical-quantum channels in two settings, for the channe…
Global Coherence in Quantum Discord as a Resource
Chellasamy Jebarathinam, Huan-Yu Ku, Hao-Chung Cheng +1
This work addresses which aspect of \textit{bipartite coherence} in \textit{quantum discord} is essential for \textit{genuinely quantum correlation}. To this end, \textit{global co…
Joint State-Channel Decoupling and One-Shot Quantum Coding Theorem
Hao-Chung Cheng, Frédéric Dupuis, Li Gao
In this work, we consider decoupling a bipartite quantum state via a general quantum channel. We propose a joint state-channel decoupling approach to obtain a one-shot error expone…
Collectively induced transparency and absorption in waveguide QED with Bragg atom arrays
Haolei Cheng, Wei Nie
Collective quantum states, such as subradiant and superradiant states, are useful for controlling optical responses in many-body quantum systems. In this work, we study novel colle…
On Strong Converse Theorems for Quantum Hypothesis Testing and Channel Coding
Hao-Chung Cheng, Li Gao
Strong converse theorems refer to the study of impossibility results in information theory. In particular, Mosonyi and Ogawa established a one-shot strong converse bound for quantu…
