# Communication over Quantum Channels with Parameter Estimation

@article{Pereg2020CommunicationOQ, title={Communication over Quantum Channels with Parameter Estimation}, author={Uzi Pereg}, journal={2020 IEEE International Symposium on Information Theory (ISIT)}, year={2020}, pages={1818-1823} }

Communication over a random-parameter quantum channel when the decoder reconstructs the parameter sequence is considered in different scenarios. Regularized formulas are derived for the capacity-distortion regions with strictly-causal, causal, or non-causal channel side information (CSI) available at the encoder, and also without CSI. Single-letter characterizations are established in special cases. In particular, a single-letter formula is given for entanglement-breaking channels when CSI is…
