Quantum technologies, divided into the technology fields of quantum sensors, quantum communication and quantum computing, offer revolutionary potential but face significant technical and economic challenges. The report describes how these technologies work and what their (potential) applications are, emphasises their opportunities and risks, and highlights the need for continuous funding. The international comparison shows that China, the USA and Europe are leading the way, with Germany playing a strong role. Despite an increasing number of publications and patent applications, many technologies are still far from commercial maturity. Recommendations for action include long-term public funding, the creation of a strategic framework and targeted support for research, development and young companies in order to realise the economic and social benefits of quantum technologies.
