- Title: Classical State Masking over a Quantum Channel
- Authors: Uzi Pereg, Christian Deppe, and Holger Boche
- Abstract summary: 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.
Regularized formula is derived for the masking equivocation region, and a full characterization is established for a class of measurement channels.

- 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.
