International conference on superconducting electronics and quantum technologies held in Erfurt

From June 16 to 19, 2025, the 19th International Superconductive Electronics Conference (ISEC) took place in Erfurt, Germany. The event brought together around 100 researchers from over 20 countries – including the USA, Japan, China, and across Europe – to discuss recent advances in superconductive electronics. Germany hosted the conference for the first time since 1997, offering a unique opportunity for Thuringia to showcase its role as a center for technological innovation.

Thuringia as a Global Hub for Superconductive Technologies

Organized by the CiS Research Institute in Erfurt and the Leibniz Institute for Photonic Technology (IPHT) in Jena, the conference was co-chaired by Prof. Thomas Ortlepp and Prof. Ronny Stolz. In his opening speech, Thuringian Minister President Mario Voigt emphasized the region’s innovation ecosystem: “In the green heart of Germany beats the technological heart of Europe.” Prof. Kai-Uwe Sattler, President of TU Ilmenau, highlighted the conference's relevance in tackling global challenges, such as the growing energy demands of AI data centers.

Technological Milestones and International Collaboration

ISEC 2025 focused on cutting-edge topics including quantum computing, single-photon detection, neuromorphic computing, and energy-efficient hardware. A highlight was the keynote by Prof. Frank Wilhelm-Mauch (Forschungszentrum Jülich), who presented the QSolid initiative – a German flagship project aiming to develop scalable solid-state quantum computers, including novel electronics for integration with classical systems.

Over four days, ISEC 2025 offered a high-profile platform for interdisciplinary exchange, scientific discussion, and the forging of international partnerships. The announcement of the next ISEC location at the close of the conference marked a continued commitment to advancing superconductive electronics on the global stage.
