Between political strategies and technological implementation, the question arises: How can quantum-secure communication already be used in practice today? The workshop provides a brief introduction to the current status at European and national level and shows which measures are already being discussed and prepared. The focus will then shift to practical application: Where are quantum-secure technologies already in use, what migration paths are open to companies, and why is it necessary to address the transition at an early stage? The aim is to make opportunities and challenges tangible and to engage in dialogue with experts.
