导线中的噪声：导线电阻对基于Johnson（类）噪声的安全通信器的实际影响
Noise in the wire: the real impact of wire resistance for the Johnson (-like) noise based secure communicator
摘要：
我们重新评估了导线电阻对基于约翰逊（类）噪声的安全通信器中噪声电压和电流的影响，纠正了[Physics Letters A 359（2006）737]中给出的结果。这里所示的分析是基于波动耗散和线性响应定理。结果表明，在实际的通信线路电阻的影响是显着低于以前的估计。
英文摘要：
We re-evaluate the impact of wire resistance on the noise voltage and current in the Johnson-(like)-noise based secure communicator, correcting the result presented in [Physics Letters A 359 (2006) 737]. The analysis shown here is based on the fluctuation-dissipation and the linear response theorems. The results indicate that the impact of wire resistance in practical communicators is significantly lower than the previous estimation.
