噪声环境中的非经典高斯态

Non-classical Gaussian states in noisy environments

Stefan Scheel, Dirk-Gunnar Welsch

摘要:

在这篇文章中,我们回顾高斯态的性质,并描述对它们的操作。作为一种特殊类型的环境相互作用的电磁场与吸收介质的相互作用将作为理解的基础上的退相干和纠缠退化的高斯态的光通过光纤传播。本文的主要内容是研究噪声环境下的量子隐形传态。特别强调的是放在问题上选择正确的位移在接收器的一方。

英文摘要:

In this article we review properties of Gaussian states and describe operations on them. The interaction of the electromagnetic field with an absorbing dielectric as a special type of environmental interaction will serve as the basis for the understanding of decoherence and entanglement degradation of Gaussian states of light propagating through fibers. The main part of the article is devoted to the study of quantum teleportation in noisy environments. Special emphasis is put onto the question of choosing the correct displacement on the receiver's side.
