广义相对熵与经典量子信道的容量

Generalized relative entropies and the capacity of classical-quantum channels

Milan Mosonyi, Nilanjana Datta

摘要:

我们提供了一个单一的使用一个经典的量子信道的信息传输容量的上下界。下限表示的Hoeffding容量,我们定义类似的Holevo容量,但取代相对熵的Hoeffding距离。类似地,我们的上限是通过用最近引入的最大相对熵代替通道发散半径定义中的相对熵而获得的量。

英文摘要:

We provide lower and upper bounds on the information transmission capacity of one single use of a classical-quantum channel. The lower bound is expressed in terms of the Hoeffding capacity, that we define similarly to the Holevo capacity, but replacing the relative entropy with the Hoeffding distance. Similarly, our upper bound is in terms of a quantity obtained by replacing the relative entropy with the recently introduced max-relative entropy in the definition of the divergence radius of a channel.
