Abstract

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 [J. Scheuer, A. Yariv, Phys. Lett. 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.
