Noise-based logic, computing and brain circuitry

Artistic animation of instantaneous noise-based logic [see papers 6-14]: RTW hyperspace operations in noise-based-logic

Some  features:

Original motive: Noise-based logic is a new approach inspired by the fact that the neural spike trains in the brain are usually stochastic.

Multivalued logic scheme, and neural circuitry (logic gates) proposed to understand the basic brain logic function.

Able to perform "intelligently": quick decisions, based on a small amount of information, with reasonably low error rate.

Exponential gain in computing performance at special-purpose computation such as with quantum algorithms.

Goal: realizing quantum algorithms with exponential speedup. All single-gate quantum gates are already realized with the same parallelism as quantum computers offer. Similar results are approached with two-bit quantum gates (needed for Shor algorithm).
