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…
Isochronous Data Link Across a Superconducting Nb Flex Cable with 5 femtojoules per Bit
Haitao Dai, Corey Kegerreis, Deepal Wehella Gamage +10
Interconnect properties position superconducting digital circuits to build large, high performance, power efficient digital systems. We report a board-to-board communication data l…
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…
True Differential Superconducting On-Chip Output Amplifier
Jonathan Egan, Andrew Brownfield, Quentin Herr
The true-differential superconductor on-chip amplifier has complementary outputs that float with respect to chip ground. This improves signal integrity and compatibility with the r…
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…
