论文摘要
我们介绍了双方量子通道的各种远期经典通信的措施。由于点对点通道是两部分通道的特殊情况，因此这些措施减少了到点对点通道的经典通信措施。事实证明，这些减少的度量已在Wang等人的先前工作中报道。在界限量子通道的经典能力上。作为应用，我们表明这些度量是双方通道的前进经典能力上的上限。减少的度量是在经典反馈通道辅助的点对点量子通道的经典容量上的上限。各种措施中的一些可以通过半准编程来计算。
We introduce various measures of forward classical communication for bipartite quantum channels. Since a point-to-point channel is a special case of a bipartite channel, the measures reduce to measures of classical communication for point-to-point channels. As it turns out, these reduced measures have been reported in prior work of Wang et al. on bounding the classical capacity of a quantum channel. As applications, we show that the measures are upper bounds on the forward classical capacity of a bipartite channel. The reduced measures are upper bounds on the classical capacity of a point-to-point quantum channel assisted by a classical feedback channel. Some of the various measures can be computed by semi-definite programming.
