The 2nd superconducting SFQ VLSI Workshop (SSV 2009)

As telecommunications equipment gets more sophisticated, the increase of power consumption is becoming a big issue. Superconductive single flux quantum (SFQ) circuits are expected to become the next-generation integrated circuits that make it possible to perform ultrahigh speed and ultralow power consumption processing, which were difficult to achieve with conventional semiconductor circuits. Research has been accelerating around the world in recent years and as the degree of integration goes up, their application has expanded to a wide variety of fields such as high-end computing, detection and processing of high-frequency signals and control of quantum computers. Also, research relating to the advancement of SFQ integrated circuit fabrication technology is ongoing. During “The 2nd Superconducting SFQ VLSI Workshop (SSV 2009)”, many researchers who are involved in the research of these SFQ integrated circuit technologies gathered and discussed about the latest research results or future challenges.

Since October 2006, research area "Low Power, High Performance, Reconfigurable Processor Using Single Flux Quantum Circuits” of “Technology Innovation and Integration for Information Systems with Ultra Low Power ” in JST CREST is proceeding with research aiming at the establishment of basic technology to create supercomputers that can be installed beside a desk by using superconducting single flux quantum circuits. At this workshop, along with the introduction of this CREST research results, the trend of research in various counties and research results of special research area “Single-Flux-Quantum Integrated Circuits Based on Localized Electromagnetic Waves” in Grant-in-Aid for Scientific Research from the Ministry of Education, Culture, Sports, Science and Technology were introduced, and active discussions were held from both aspects of digital application and fabrication technology regarding SFQ integrated circuit technology.

This workshop was held ahead of “The 12th International Superconductive Electronics Conference (ISEC2009)” held at the same venue from June 17 to June 19, and a special session was also planned during ISEC2009. In the afternoon of June 15 and the morning of June 16, 14 lectures including 4 lectures by invited speakers were held in 2 sessions, and poster presentations on 17 themes were also held. In the afternoon of June 16, a joint workshop was held with the “JSPS 146 Committee on Superconductive Electronics” of Japan Society for the Promotion of Science, and there were 3 lectures by invited guests during this SSV session. Furthermore, in the morning of June 17, 7 presentations were held in ISEC2009 special SSV session regarding signal processing.

By collaborating with ISEC2009, we were joined by a total of over 400 researchers from a wide range of fields regarding superconducting electronics from Japan and abroad.
