One-Shot Hybrid State Redistribution

We consider state redistribution of a hybrid information source that has both classical and quantum components. The sender transmits classical and quantum information at the same time to the receiver, in the presence of classical and quantum side information both at the sender and at the decoder. The available resources are shared entanglement, and noiseless classical and quantum communication channels. We derive one-shot direct and converse bounds for these three resources, represented in terms of the smooth conditional entropies of the source state. Various coding theorems for two-party source coding problems are systematically obtained by reduction from our results, including the ones that have not been addressed in previous literatures.

Automated summary

This study investigates state redistribution of a hybrid information source that consists of both classical and quantum components. It explores the transmission of classical and quantum information simultaneously, using shared entanglement and noiseless classical and quantum communication channels. The study presents direct and converse bounds for these three resources based on the smooth conditional entropies of the source state. It also derives various coding theorems for two-party source coding problems, some of which have not been addressed in previous literature.
