Materials that can conduct electricity without resistance and thus without loss - so-called superconductors - promise a wide range of modern applications - from nuclear spin tomographs to high-precision measurement technology and quantum computers to integrated circuits and sensor systems for extremely energy-efficient, ultrafast information technology, so-called " green electronics ". However, researchers worldwide still face numerous challenges such as efficient cooling to very low temperatures and increasing the complexity of integrated circuits so that digital superconducting electronics can be applied efficiently and cost-effectively.
Current developments in digital superconducting electronics are therefore the focus of the 12th FLUXONICS Digital Superconducting Electronics Workshop at TU Ilmenau, which this week brings together world-leading scientists and representatives of technology companies in this field: At the Center for Microand Nanotechnologies (ZMN) , a total of 46 participants from Belgium, China, Turkey, France, Japan, South Africa, the USA and Germany will spend three days discussing the latest achievements and experiences in the application of superconducting electronics.
The workshop is organized by the Advanced Electromagnetics Group headed by Prof. Hannes Töpfer in collaboration with Prof. Ronny Stolz , Head of the Quantum Systems Research Department at the Leibniz Institute for Photonic Technologies (Leibniz-IPHT) Jena and Honorary Professor of Quantum Engineering at the TU Ilmenau. As a design center of the European research network of superconductor electronics (FLUXONICS ), the department has been conducting research in the field of low-loss, high-speed electronics for several decades and is a global leader, especially in the development of so-called single-flux quantum integrated circuits.
Together with other high-ranking researchers, the Thuringian scientists will convey the physical fundamentals of modern superconductor electronics in the workshop, discuss circuit architectures and present the state of the feasibility of superconducting energy-efficient electronics.
"We are particularly pleased to welcome Prof. Nobuyuki Yoshikawa and his team from Yokohama National University in Japan to our university," said Prof. Töpfer. Prof. Yoshikawa has just been awarded the IEEE Council of Superconductivity (CSC) Award for Continuing and Significant Contribution in the Field of Applied Superconductivity for his research on the development of the so-called adiabatic quantum flux parametron logic, currently the most energy-efficient practically demonstrated digital circuit technique. This makes Noboyuki Yoshikawa one of the leading researchers in the field of "Green Electronics", a research focus at ZMN.
