Journal ArticleDOI
An adiabatic quantum flux parametron as an ultra-low-power logic device
TL;DR: In this article, an ultra-low-power adiabatic quantum flux parametron (QFP) logic is investigated, which has the potential to reduce the bit energy per operation to the order of the thermal energy.
Journal ArticleDOI
Nb 9-Layer Fabrication Process for Superconducting Large-Scale SFQ Circuits and Its Process Evaluation
Shuichi Nagasawa,K. Hinode,Tetsuro Satoh,Mutsuo Hidaka,Hiroyuki Akaike,Akira Fujimaki,Nobuyuki Yoshikawa,Kazuyoshi Takagi,Naofumi Takagi +8 more
TL;DR: The results show that considerable progress has been made in reducing the number of defects and improving reliability on a Nb nine-layer fabrication process for large-scale single flux quantum (SFQ) circuits.
Journal ArticleDOI
Data-driven self-timed RSFQ digital integrated circuit and system
TL;DR: Test results of a 4-bit DDST shift register and a high speed on-chip clock generator will be presented to demonstrate the successful DDST operation of RSFQ integrated circuits at a rate of 20 Gb/s.
Journal ArticleDOI
Adiabatic quantum-flux-parametron cell library designed using a 10 kA cm−2 niobium fabrication process
Naoki Takeuchi,Naoki Takeuchi,Shuichi Nagasawa,Fumihiro China,Takumi Ando,Mutsuo Hidaka,Yuki Yamanashi,Nobuyuki Yoshikawa +7 more
TL;DR: In this paper, a new AQFP cell library was designed using the AIST 10 kA cm−2 Nb high-speed standard process (HSTP), which is a high-critical-current-density version of the standard process.
