Scaling NbTiN-based ac-powered Josephson digital to 400M devices/cm
Anna Herr, Quentin Herr, Steve Brebels +9
We describe a fabrication stackup for digital logic with 16 superconducting NbTiN layers, self-shunted a-silicon barrier Josephson Junctions (JJs), and low loss, high- tunable H…
Superconducting Pulse Conserving Logic and Josephson-SRAM
Quentin Herr, Trent Josephsen, Anna Herr
Superconducting digital Pulse-Conserving Logic (PCL) and Josephson SRAM (JSRAM) memory together enable scalable circuits with energy efficiency 100x beyond leading-node CMOS. Circu…
Synchronous Chip-to-Chip Communication with a Multi-Chip Resonator Clock Distribution Network
Jonathan Egan, Max Nielsen, Joshua Strong +5
Superconducting digital circuits are a promising approach to build packaged-level integrated systems with high energy-efficiency and computational density. In such systems, perform…
Measurement and Data-Assisted Simulation of Bit Error Rate in RQL Circuits
Quentin Herr, Alex Braun, Andrew Brownfield +4
A circuit-simulation-based method is used to determine the thermally-induced bit error rate of superconducting logic circuits. Simulations are used to evaluate the multidimensional…
Propagation of Picosecond Pulses on Superconducting Transmission Line Interconnects
Vladimir V. Talanov, Derek Knee, David Harms +5
Interconnects are a major discriminator for superconducting digital technology, enabling energy efficient data transfer and high-bandwidth heterogeneous integration. We report a me…
