加性相关经典噪声下的量子高斯信道
Quantum Gaussian Channels with Additive Correlated Classical Noise
摘要:
我们提供了一个模型来研究记忆效应在量子高斯信道加性经典噪声在任意数量的使用。不同用途之间的相关性是由连续的双模式交互作用引入的。少数模式的数值结果。他们确认的可能性,以提高经典的信息速率与纠缠输入的帮助下,并显示可能的渐近行为,应导致信道的全部容量。
英文摘要:
We provide a model to study memory effects in quantum Gaussian channels with additive classical noise over an arbitrary number of uses. The correlation among different uses is introduced by contiguous two-mode interactions. Numerical results for few modes are presented. They confirm the possibility to enhance the classical information rate with the aid of entangled inputs, and show a likely asymptotic behavior that should lead to the full capacity of the channel.
