机密直接通信:使用连续变量的量子方法

Confidential direct communications: a quantum approach using continuous variables

Stefano Pirandola, Samuel L. Braunstein, Seth Lloyd, Stefano Mancini

摘要:

我们考虑直接通信中的隐私问题,展示了量子力学如何能够用于保证一定程度的保密性。特别地,我们回顾了我们最近提出的连续变量方法[S. Pirandola等人,欧罗巴Lett. 84,20013(2008)]。在这里,我们分析了这种技术对更广泛的攻击,其中包括非高斯窃听的隐私程度。

英文摘要:

We consider the problem of privacy in direct communications, showing how quantum mechanics can be useful to guarantee a certain level of confidentiality. In particular, we review a continuous variable approach recently proposed by us [S. Pirandola et al., Europhys. Lett. 84, 20013 (2008)]. Here, we analyze the degree of privacy of this technique against a broader class of attacks, which includes non-Gaussian eavesdropping.
