Query: Stochastic single flux quantum neuromorphic computing using magnetically
  tunable Josephson junctions   Single flux quantum (SFQ) circuits form a natural neuromorphic technology
with SFQ pulses and superconducting transmission lines simulating action
potentials and axons, respectively. Here we present a new component, magnetic
Josephson junctions, that have a tunablility and re-configurability that was
lacking from previous SFQ neuromorphic circuits. The nanoscale magnetic
structure acts as a tunable synaptic constituent that modifies the junction
critical current. These circuits can operate near the thermal limit where
stochastic firing of the neurons is an essential component of the technology.
This technology has the ability to create complex neural systems with greater
than 10^21 neural firings per second with approximately 1 W dissipation.
