Noise-based logic
From Wiki @ Karl Jones dot com
Noise-based logic (NBL) is a class of many-valued logic schemes where the logic values and bits are represented by different realizations of a stochastic process.
The concept of noise-based logic and its name was created by Laszlo B. Kish. In its foundation paper[3] it is noted that the idea was inspired by the stochasticity of brain signals and by the unconventional noise-based communication schemes, such as the Kish cypher.
