The Quantum Technologies Flagship, officially launched on 29 October 2018 in Vienna, is a EUR 1 billion initiative, supported by the European Commission and Member States, funding over 5,000 of Europe's leading Quantum Technologies researchers over the next ten years and aiming at placing Europe at the forefront of the second quantum revolution. Its long-term vision is to develop a quantum web, where quantum computers, simulators and sensors are interconnected via quantum communication networks. This will help kick-starting a competitive European quantum industry transforming research results into commercial applications and disruptive technologies. \nThe Joint Research Center (JRC) in cooperation with the European Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization (CENELEC), European Commission’s Directorate General Communications Networks, Content and Technology (DG CNECT), and the German Institute of Standardisation (DIN), organised in Brussels on 28-29 March 2019 the Putting-Science-Into-Standards (PSIS) workshop on Quantum Technologies. The PSIS workshops is an initiative that brings together researchers, industry and standardisers with the purpose of facilitating the identification and screening of emerging science and technology areas that can be introduced early into the process of standardisation to enable innovation.\nThe experience with the innovation impact pathway of the Graphene Flagship that combined technology push and market pull by working with industry stakeholders was used to demonstrate the benefit of a strategic use of standardisation to increase technology readiness levels and reach the market.\nThe participants of the workshop identified aspects that would benefit from standardisation activities in three main areas: (i) Quantum Key Distribution and quantum-safe security, (ii) Quantum metrology, sensing and imaging, (iii) and Quantum computing and internet. Several existing standardisation activities focussing on quantum enabled security techniques, quantum computing and communication were also mapped. With the direct involvement of the participants, the workshop prepared the ground towards a roadmap of additional pressing technology fields where standardisation could add value to the deployment of Quantum Technologies in industrial applications, including security, sensing, imaging and measurement. \nAn active dialogue between the communities of researchers and standardisers as well as a continuous interchange with the Quantum Technologies Flagship would be beneficial for future interactions and cooperation. The Standards, Innovation and Research Platform (STAIR / CEN and CENELEC) methodology could constitute a straightforward approach to host interactions between the communities of researchers and standardisers.\nNext steps would be to start an interaction (e.g. a cooperation agreement) with the Quantum Flagship and in particular with the recently (April 2019) launched Coordination and Support Action of the Quantum Flagship. As concrete actions for standardisation, the workshop suggested to focus on the standardisation of a quantum technology terminology and on the development of an EU standardisation roadmap for Quantum Technologies. These could be addressed by a European Committee for Standardization workshop or by a focus group.

Quantum technologies represent a new agenda that has the potential to fundamentally change the security environment on aglobal scale. Countries or groups of countries that adopt these technologies before others will be at an advantage. The aim ofthe authors was to provide an overview of the current status of creating conditions for the development of quantum technologies in selected Central European countries (Czech Republic, Slovakia, Austria, Hungary and Slovenia). The studymaps the conceptual, organisational and technical situation in this area, focusing on the five North Atlantic Treaty Organisation member states and the European Union. As a result of the investigation, it is found that the complexity of quantum technologies requires cooperation at two levels. The first level is undoubtedly cooperation between the state sector,scientific organisations, the defence sector and multinational companies. The second level is cooperation between individual states or within international organisations. Regarding the security aspects of these technologies, cooperation based on North Atlantic Treaty Organisation and European Union is crucial. Ensuring technological superiority in the coming years is a big challenge for the United States of America, resp. North Atlantic Treaty Organisation and the European Union.

Abstract In 2025, the Year of Quantum Science and Technology ( https://quantum2025.org/ ), we celebrate a century of quantum mechanics, witnessing a surge in activities that illuminate its inherent strangeness and drive technological innovation. Superconductivity, discovered 114 years ago, stands as a prime example, offering direct and compelling evidence of macroscopic quantum phenomena. Beyond its ability to conduct immense currents without loss, superconductivity reveals the quantum realm operating on a scale we can directly observe and manipulate. The macroscopic quantum coherence, where an ensemble of particles is described by a single wave function, leads to remarkable consequences: dissipation-less current and flux quantization—the basic properties exploited in superconducting quantum circuit fabrication. This Roadmap has been inspired by intensive discussions and collaborations emerging from the European Cooperation in Science & Technology COST-Action CA21144 (SuperQuMap—Superconducting Nanodevices and Quantum Materials for Coherent Manipulation). The aim of the COST Action SuperQuMap is to establish a strong European network centered on macroscopic quantum behavior in superconductors, bringing together groups of different backgrounds and more than 30 countries. The roadmap outlines the network’s concrete activities, driving advancements in superconductor-based quantum technologies and charting future directions. Spanning fundamental research to practical applications, the roadmap incorporates insights from industry partners developing quantum computation. It begins by exploring quantum materials, highlighting how topology and electronic correlations could catalyze a quantum leap in technology. We then delve into manipulating the superconducting phase, leveraging advancements in magnetism, 3D fabrication, and tunable correlations. Further, we showcase the advanced microscopy techniques—such as angle-resolved photoemission spectroscopy and scanning probes—used to visualize quantum behavior. Finally, and crucially, we detail the quantum devices developed within the network, and their transformative impact on modern quantum computing approaches.
