Quantum Effects already exceeded expectations after its premiere in 2023, and its second edition in 2024 closed with a significant increase in participants. It is now regarded as the world's leading trade fair and conference for application-oriented quantum technologies and takes place every year.

From 7 – 8 October 2025, the international quantum industry and politics will meet in Stuttgart to discuss the latest developments and challenges in the industry. World market leaders and application industries are thus promoting international cooperation and strengthening Europe's sovereignty in the global quantum landscape. The event generates enthusiasm for quantum technologies and offers an ideal platform for innovation, inspiration and collaboration. Together with industry, science, politics and relevant partners, a comprehensive quantum network is being developed and designed.

By combining an exhibition, conference for science and industry users and the start-up pitch and careers areas, Quantum Effects offers an attractive program for the trade audience, with highlights such as the forum for presenting exhibitors’ showcases and application examples.

The centerpiece is the first-class conference program, which includes scientific lectures for experts and user presentations for industry, management and politicians. Beyond this core element, the accompanying program of forums, networking and career area, workshops and start-up pitches rounds off the event.

The fair’s main target attendee groups include representatives of small and medium-sized enterprises, as well as large companies. The trade fair combined with conference is aimed equally at companies that have already initiated quantum technology projects and those that are not yet active in the market, but are interested in building up expertise in this field. Students and academics from universities and academies are also part of the target group, as are political leaders at state, national and EU level.
