Noise in the wire: The real impact of wire resistance for the Johnson(-like) noise based secure communicator Academic Article uri icon

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. 2010 Elsevier B.V. All rights reserved.
