TL;DR: A new form of artificial synapse based on dynamically reconfigurable superconducting Josephson junctions with magnetic nanoclusters in the barrier is demonstrated, which provides a significant step toward a neuromorphic platform that is faster, more energy-efficient, and thus can attain far greater complexity than has been demonstrated with other technologies.

TL;DR: An amplifier chain that converts the current pulse generated when a neuron reaches threshold to a voltage pulse sufficient to produce light from a semiconductor diode is described, and it is shown that a synaptic weight can be modified via a superconducting flux-storage loop inductively coupled to the current bias of the synapse.

TL;DR: A new component, magnetic Josephson junctions, that have a tunablility and re-configurability that was lacking from previous SFQ neuromorphic circuits are presented.

TL;DR: In this article, a new component, magnetic Josephson junctions, is presented, which has a tunablility and reconfigurability that was lacking from previous single flux quantum (SFQ) neuromorphic circuits.

TL;DR: In this paper, a programmable reference source is proposed to synthesize spectrally pure waveforms with quantum-based voltage accuracy for characterizing and improving future communication devices and systems.
