Researchers have fabricated two- and three-junction superconducting quantum interferometers based on gold nanowires, which can be used for implementing bio-inspired neurons. Their operation modes have been investigated experimentally and theoretically, and compared with the mathematical model of biological neurons proposed by Izhikevich.
High-performance modeling of neurophysiological processes is an urgent task that requires new approaches to information processing. In this context, two- and three-junction superconducting quantum interferometers with Josephson weak links based on gold nanowires are fabricated and investigated experimentally. The studied cells are proposed for the implementation of bio-inspired neurons-high-performance, energy-efficient, and compact elements of neuromorphic processor. The operation modes of an advanced artificial neuron capable of generating the burst firing activation patterns are explored theoretically. A comparison with the Izhikevich mathematical model of biological neurons is carried out.
