量子信道态掩蔽

Quantum Channel State Masking

Uzi Pereg, Christian Deppe, Holger Boche

摘要:

当编码器具有信道侧信息(CSI)并且需要从解码器屏蔽关于量子信道状态的信息时,考虑依赖于量子状态的量子信道上的通信。给出了纠缠辅助掩蔽含糊区的完整刻画,并给出了无辅助掩蔽含糊区量子容量泄漏函数的正则化公式。对于阿达玛渠道没有援助,我们推导出单字母的内部和外部的界限,这符合在标准的情况下,不依赖于一个国家的通道。

英文摘要:

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.
