Noise-based logic
Noise-based logic (NBL)〔 is a new class of multivalued deterministic 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〔 〕 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 ).
==The noise-based logic space and hyperspace==
The logic values are represented by multi-dimensional "vectors" (orthogonal functions) and their superposition, where the orthogonal basis vectors are independent noises. By the proper combination (products or set-theoretical products) of basis-noises, which are called ''noise-bit'', a logic hyperspace can be constructed with number of dimensions, where ''N'' is the number of noise-bits. Thus ''N'' noise-bits in a single wire correspond to a system of classical bits that can express different logic values. Independent realizations of a stochastic process of zero mean have zero cross-correlation with each other and with other stochastic processes of zero mean. Thus the basis noise vectors are orthogonal not only to each other but they and all the noise-based logic states (superpositions) are orthogonal also to any background noises in the hardware. Therefore, the noise-based logic concept is robust against background noises, which is a property that can potentially offer a high energy-efficiency.
