FLUXONICS is a european framework dedicated to furthering research into superconducting electronics and digital circuits. Within this framework is the S-Pulse project, which I am currently involved in. As part of this project, I recently visited the FLUXONICS foundry for superconducting electronics at IPHT, Jena for a Technology training workshop.
There are several institutions involved in the project, and it was interesting to meet people from all over Europe who share a similar interest in this technology:
University of Twente (The Netherlands)
Chalmers Univ. of Technology (Sweden)
University of Savoie (France)
University of Cambridge (UK)
University of Birmingham (UK)
CNR-Istituto di Cibernetica (Italy)
University of Technology Ilmenau (Germany)
University of Karlsruhe (Germany)
It was a good workshop, with a thorough introduction to RSFQ and the state of superconducting electronics in Europe. The foundry has a stable 1 kA/cm2 Nb/Al-AlOx/Nb process certified with ISO-9001 standard. It is nice to see this activity in Europe, given that the other two major superconducting electronics foundries are based in America (HYPRES) and Japan (ISTEC). It will be interesting to see how the European RSFQ / Josephson technology improves over the next couple of years, and to keep track of the research performed with chips fabricated using the IPHT Niobium process.
