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. Quantum Effects 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.
