量子多址信道的容量定理

Capacity Theorems for Quantum Multiple Access Channels

Jon Yard, Igor Devetak, Patrick Hayden

摘要:

我们考虑具有两个接收器和一个接收器的量子信道。对于任意的这样的信道,我们给出了两个不同的二维容量区域的多字母特征。第一个区域表征了一个发送者发送经典信息而另一个发送量子信息的速率。第二个区域给出了每个发送者可以发送量子信息的速率。我们给出了一个例子的通道,每个区域有一个单字母的描述,最后与表征的速率,每个用户可以同时发送经典和量子信息。

英文摘要:

We consider quantum channels with two senders and one receiver. For an arbitrary such channel, we give multi-letter characterizations of two different two-dimensional capacity regions. The first region characterizes the rates at which it is possible for one sender to send classical information while the other sends quantum information. The second region gives the rates at which each sender can send quantum information. We give an example of a channel for which each region has a single-letter description, concluding with a characterization of the rates at which each user can simultaneously send classical and quantum information.
