论文摘要
当需要解码器重建参数序列时，通过随机参数量子通道进行通信。我们研究了包括严格的果酱，因果或非毒物通道侧信息（CSI），以及何时不可用CSI。该模型可以看作是量子计量学的一种形式，并且是经典速率和状态通道的量子对应物，并在解码器处进行状态估计。得出了容量延伸区域的正则公式。在测量通道的特殊情况下，为严格的因果和因果设置得出了单个字母的特征。此外，在更一般的破坏纠缠通道的情况下，当CSI不可用时，将得出单个字母的特征。结果，我们获得了使用CSI随机参数量子通道的能力的正则公式，从而概括了Boche等人的先前结果。 （2016）在古典量子频道上。
Communication over a random-parameter quantum channel when the decoder is required to reconstruct the parameter sequence is considered. We study scenarios that include either strictly-causal, causal, or non-causal channel side information (CSI) available at the encoder, and also when CSI is not available. This model can be viewed as a form of quantum metrology, and as the quantum counterpart of the classical rate-and-state channel with state estimation at the decoder. Regularized formulas for the capacity-distortion regions are derived. In the special case of measurement channels, single-letter characterizations are derived for the strictly causal and causal settings. Furthermore, in the more general case of entanglement-breaking channels, a single-letter characterization is derived when CSI is not available. As a consequence, we obtain regularized formulas for the capacity of random-parameter quantum channels with CSI, generalizing previous results by Boche et al. (2016) on classical-quantum channels.
