论文摘要
考虑了量子广播渠道的识别。与信息传输任务相反，解码器仅确定是否发送其选择的消息。这种放松允许双指数代码大小。为量子广播通道提供了可实现的识别区域，并为经典量词广播渠道提供了完整的表征。因此，获得了单模纯净骨传播通道的识别能力区域。此外，在我们地区次优的量子擦除广播通道中证明了结果，但改善了以前已知的界限。
Identification over quantum broadcast channels is considered. As opposed to the information transmission task, the decoder only identifies whether a message of his choosing was sent or not. This relaxation allows for a double-exponential code size. An achievable identification region is derived for a quantum broadcast channel, and a full characterization for the class of classical-quantum broadcast channels. The identification capacity region of the single-mode pure-loss bosonic broadcast channel is obtained as a consequence. Furthermore, the results are demonstrated for the quantum erasure broadcast channel, where our region is suboptimal, but improves on the best previously known bounds.
