利用高斯态发送量子信息

Sending Quantum Information with Gaussian States

Alexander S. Holevo

摘要:

对输入为高斯态的玻色子衰减/放大信道,计算了量子互信息、损耗、噪声和相干信息等量子信息特性。相干信息示出为负的衰减系数$k<1/\sqrt{2}$的值。

英文摘要:

Quantum information characteristics, such as quantum mutual information, loss, noise and coherent information are explicitly calculated for Bosonic attenuation/amplification channel with input Gaussian state. The coherent information is shown to be negative for the values of the attenuation coefficient $k<1/\sqrt{2}$.
