Title:Classical State Masking over a Quantum Channel

Authors:Uzi Pereg, Christian Deppe, Holger Boche
View PDF
Abstract:Transmission of classical information over a quantum state-dependent channel is considered, when the encoder can measure channel side information (CSI) and is required to mask information on the quantum channel state from the decoder. In this quantum setting, it is essential to conceal the CSI measurement as well. A regularized formula is derived for the masking equivocation region, and a full characterization is established for a class of measurement channels.
