Transport and Channel Normal Forms for Clifford Interactions

We study how Clifford interactions with a fixed environment determine quantum transmission, in a setting that extends positive discrete quantum convolution . We characterize when Clifford operations on the environment can be replaced by operations on the signal input and the two outputs, and classify the interactions u...

Mean-State Entropy Hierarchies and Classical Communication through Quantum Convolutions

A finite-step entropy hierarchy generated by compatible stabilizer dephasings is established, characterized by the entropy hierarchy and refines the previous mean-state bound of Bu, Gu, and Jaffe.
