Quantum Effects, the new trade fair and conference for quantum technologies, took place for the first time at the Stuttgart Exhibition Centre from 10 to 11 October 2023. As one of the 70 exhibitors, Quantum Valley Lower Saxony presented the progress made in Lower Saxony’s growing quantum science and quantum economy. The successes in industry transfer with the high-tech incubator (QVLS HTI) and the Zukunftscluster iLabs were particularly well received by the community of almost 2,500 visitors from science, industry and politics.
