Stochastic single flux quantum neuromorphic computing using magnetically tunable Josephson junctions
S. E. Russek, C. A. Donnelly, M. L. Schneider +6
Single flux quantum (SFQ) circuits form a natural neuromorphic technology with SFQ pulses and superconducting transmission lines simulating action potentials and axons, respectivel…
Spin-transfer torque switching in nanopillar superconducting-magnetic hybrid Josephson junctions
Burm Baek, William H. Rippard, Matthew R. Pufall +4
The combination of superconducting and magnetic materials to create novel superconducting devices has been motivated by the discovery of Josephson critical current (Ics) oscillatio…
Hybrid superconducting-magnetic memory device using competing order parameters
Burm Baek, William H. Rippard, Samuel P. Benz +2
Superconducting devices, which rely on modulating a complex superconducting order parameter in a Josephson junction, have been developed for low power logic operations, high-freque…
Switching Distributions for Perpendicular Spin-Torque Devices within the Macrospin Approximation
W. H. Butler, T. Mewes, C. K. A. Mewes +4
We model "soft" error rates for writing (WSER) and for reading (RSER) for perpendicular spin-torque memory devices by solving the Fokker-Planck equation for the probability distrib…
Thermal Relaxation Rates of Magnetic Nanoparticles in the Presence of Magnetic Fields and Spin-Transfer Effects
William Rippard, Ranko Heindl, Matthew Pufall +2
We have measured the relaxation time of a thermally unstable ferromagnetic nanoparticle incorporated into a magnetic tunnel junction (MTJ) as a function of applied magnetic field,…
Design and Testing of Superconducting Microwave Passive Components for Quantum Information Processing
H. S. Ku, F. Mallet, L. R. Vale +4
We report on the design, fabrication and testing of two superconducting passive microwave components, a quadrature hybrid and a 20 dB directional coupler. These components are desi…
