Single-flux-quantum circuits for spiking neuron devices

Single-flux-quantum (SFQ) circuits can be used for making spiking neuron devices, which are useful elements for constructing intelligent, brain-like computers. The device we propose is based on the integrate-and-fire neuron model and uses an SFQ pulse as an action signal or a spike of neurons. Computer simulation has shown that the device successfully operated with a short delay of 100 ps or less. It is the highest-speed neuron device ever reported.
