Noise-Driven Informatics: Secure Classical Communications via Wire and Noise-Based Computing

Chapter

Abstract

In this paper, we show recent results indicating that using electrical noise as information carrier offers outstanding potentials reminding of quantum informatics. One example is noise-based computing and logic that shows certain similarities to quantum logic. However, due to the lack of the collapse of wavefunction and due to the immediate accessibility of superposition components, the use of noise-based and quantum computers will probably be different. Another example is secure communications where, out of the unconditional security at idealistic situations, a practical security beyond known quantum solutions can be achieved and has been demonstrated. Here, the keys to security are the robustness of the classical information, which results in the avoidance of using error statistics, and the second law of thermodynamics.

Acknowledgments

Comments of Gabor Schmera about the draft are appreciated. Zoltan Gingl is grateful for the Bolyai Fellowship of Hungarian Academy of Sciences. The travel of LBK to the University of Szeged for the startup phase of the experiments was covered by the Swedish STINT foundation and the cost of staying (10–15 December 2006) was partially covered by the European Union’s SANES grant. The costs of the KLJN system design were partially covered by the TAMU Information Technology Task Force (TITF, grant 2002). Part of these results was submitted to Physics Letters A [10].
