Mean-State Entropy Hierarchies and Classical Communication through Quantum Convolutions
Chunhe Xiong, Sunho Kim, Qing-hua Zhang +2
Quantum convolution provides a discrete-variable analogue of classical convolution, with the mean state capturing the stabilizer structure preserved under repeated convolution. We…
Private Capacity of Quantum Channels Induced by Non-stabilizer Environmental States
Chunhe Xiong, Sunho Kim, Long Long +1
The paper analyzes how the private capacity of quantum channels depends on the nature of the environmental state, showing that stabilizer environments yield zero private capacity w…
A Deficiency-Based Approach for the Operational Interpretation of Quantum Resources with Applications
Sunho Kim, Chunhe Xiong, Junde Wu
A fundamental challenge in quantum resource theory is to establish operational interpretations by quantifying the advantage that quantum resources provide in specific tasks. Conven…
Quanutm-State Texture as a Resource: Measures and Nonclassical Interdependencies
Yuntao Cui, Zhaobing Fan, Sunho Kim
Quantum-state texture is a newly recognized quantum resource that has garnered attention with the advancement of quantum theory. In this work, we address several key aspects of qua…
Relative Quantum Resource Theory and Operational Applications in Subchannel Discrimination
Sunho Kim, Chunhe Xiong, Junde Wu
A central problem in quantum resource theory is to give operational meaning to quantum resources that can provide clear advantages in certain physical tasks compared to the convex…
