Quantum Channel State Masking
Communication over a quantum channel that depends on a quantum state is
considered when the encoder has channel side information (CSI) and is required
to mask information on the quantum channel state from the decoder. A full
characterization is established for the entanglement-assisted masking
equivocation region, and a regularized formula is given for the quantum
capacity-leakage function without assistance. For Hadamard channels without
assistance, we derive single-letter inner and outer bounds, which coincide in
the standard case of a channel that does not depend on a state
