Noise-based logic

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.

Thus N noise-bits in a single wire correspond to a system of 2N classical bits that can express 22N different logic values.

Therefore, the noise-based logic concept is robust against background noises, which is a property that can potentially offer a high energy-efficiency.

Later, in the instantaneous noise-based logic schemes[6][7] and computation works,[8] random telegraph waves (periodic time, bipolar, with fixed absolute value of amplitude) were also utilized as one of the simplest stochastic processes available for NBL.

The string verification work[8] over a slow communication channel shows a powerful computing application where the methods is inherently based on calculating the hash function.
