Superconductor digital electronics using Josephson junctions as ultrafast switches and
magnetic-flux encoding of information was proposed over 30 years ago as a sub-terahertz …

Conventional semiconductor-based digital electronics, with complementary metal oxide
semiconductor (CMOS) technology as the primary example, has experienced meteoric …

Power and energy consumed by a high-performance computing system are a significant
problem nowadays. Superconducting computing technology may offer an attractive low …

We have designed and tested at high frequency an RSFQ-based Arithmetic-Logic Unit
(ALU), the critical component of an 8-bit RSFQ processor datapath. The ALU design is …

We have designed and tested a parallel 8-bit ERSFQ arithmetic logic unit (ALU). The ALU
design employs wave-pipelined instruction execution and features modular bit-slice …

The objective of these notes is to offer a brief review of the history of superconductor digital
electronics, and discuss prospects of its future development. Due to length restrictions, many …

The ColdFlux project, within the IARPA SuperTools program, aims to develop an open-
source EDA tool suite for superconductor circuits, with focus on Rapid single flux quantum …

This paper presents a path balancing technology map** algorithm, which is a new
algorithm for generating a map** solution for a given Boolean network such that the …

We have developed a cell library for superconducting large scale integrated (LSI) digital
circuits based on Single Flux Quantum (SFQ) devices. The circuits were designed for a 6 …

Superconducting integrated circuits (ICs) based on Josephson junctions (JJs) and
superconducting materials subvert semiconductor ICs at the device level. For over 50 years …
