Europe’s quantum technology landscape has evolved from disparate academic projects into a coordinated multi-billion euro endeavor encompassing the EU and its member states. The historical commitment to quantum science is now manifesting in tangible outputs: prototype quantum computers in laboratories and supercomputing centers, quantum-secure communication testbeds linking cities, and quantum sensors poised to revolutionize measurements from under the Earth to outer space. The European Union’s flagship program and national quantum strategies in Germany, France, the Netherlands, and elsewhere have created a momentum that engages both prestigious research institutions (ETH Zurich, CNRS, Max Planck Society, etc.) and a growing quantum startup sector (Pasqal, IQM, Atos, and many more) ...
