量子高斯记忆通道的跃迁行为

On the transitional behavior of quantum Gaussian memory channels

C. Lupo, S. Mancini

摘要:

讨论了量子高斯存储通道中纠缠输入态的最优性问题。对于一类这样的通道,可以追溯到无记忆的设置,我们状态的标准有关的纠缠输入的最优性的对称性的通道的行动。属于这一类的通道模型的几个例子进行了讨论。

英文摘要:

We address the question of optimality of entangled input states in quantum Gaussian memory channels. For a class of such channels, that can be traced back to the memoryless setting, we state a criterion which relate the optimality of entangled inputs to the symmetry properties of the channels' action. Several examples of channel models belonging to this class are discussed.
