Transport and Channel Normal Forms for Clifford Interactions
Xiong Chunhe, Kim Sunho, Zhang Qing-Hua +2
We study how Clifford interactions with a fixed environment determine quantum transmission, in a setting that extends positive discrete quantum convolution . We characterize when C…

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
We investigate the private capacity of quantum channels using the recently proposed quantum convolution theory for discrete-variable quantum systems. We focus on the role of the ma…
