Belousov-Zhabotinsky (BZ) reaction computer
f(x) = boolean logic / reaction-diffusion computation (via chemical wave collisions)
The BZ reaction is an oscillating chemical system that produces propagating excitation waves in a thin layer of reagent (typically ferroin or ruthenium catalyst in acidified bromate/malonate). Signals...
BrainScaleS wafer-scale neuromorphic system
f(x) = accelerated analog spiking neural network emulation
BrainScaleS wafer-scale neuromorphic system blends analog wafer-scale integrators with digital control, forming the EBRAINS neuromorphic computing service for fast emulation of spiking neural networks...
DNA strand-displacement computer
f(x) = boolean logic / neural network inference (via hybridization cascades)
Single-stranded DNA molecules in solution compute via toehold-mediated strand displacement: a short single-stranded 'toehold' on a partially double-stranded gate complex allows an input strand to inva...
