New technologies for communications, computing, sensing and timing, which exploit quantum physics more deeply than heretofore, are expected to have high impact and to require a European policy response. This paper raises key discussion points, as a contribution to a wider EC initiative.
Recently, the European Commission supported by many European countries has announced large investments towards the commercialization of quantum technology (QT) to address and mitigate some of the biggest challenges facing today's digital era - e.g. secure communication and computing power. For more than two decades the QT community has been working on the development of QTs, which promise landmark breakthroughs leading to commercialization in various areas. The ambitious goals of the QT community and expectations of EU authorities cannot be met solely by individual initiatives of single countries, and therefore, require a combined European effort of large and unprecedented dimensions comparable only to the Galileo or Copernicus programs. Strong international competition calls for a coordinated European effort towards the development of QT in and for space, including research and development of technology in the areas of communication and sensing. Here, we aim at summarizing the state of the art in the development of quantum technologies which have an impact in the field of space applications. Our goal is to outline a complete framework for the design, development, implementation, and exploitation of quantum technology in space.
Quantum technologies are increasingly recognized as a disruptive frontier that will shape the next generation of industrial strategies. Developments in quantum computing, communication, and sensing promise not only technical breakthroughs but also significant economic and geopolitical consequences. Quantum computing can accelerate drug discovery, materials research, and complex optimization, while quantum communication opens new possibilities for secure data transfer beyond the reach of classical encryption. According to European Commission Reports and National Quantum Initiative Act, leading economies are already investing heavily: the European Union has committed over €1 billion to its Quantum Flagship program, while the United States launched the National Quantum Initiative Act in 2018 to coordinate research and industrial applications. These initiatives underscore the strategic nature of the field. For industrial policy, they also raise important questions: How should governments design roadmaps that foster public–private collaboration? What forms of regulation or incentives are needed to align innovation with competitiveness and security? At the same time, quantum technologies could support sustainability goals, for example through energy-efficient algorithms and advanced climate modeling. Positioning quantum technologies not only as an enabler but as a driver of future industrial policy is essential. Unlike incremental innovations, quantum breakthroughs will actively shape the direction of national strategies, global competitiveness, and sustainability agendas. Recognizing this driver role ensures that policymakers and industries move beyond adaptation, taking a proactive stance in designing resilient and forward-looking industrial ecosystems.
This report describes a survey of opinions in relevant technology communities regarding the best options for research and development of quantum computing, the likely impact on various sectors, and the expected timescales. The survey is intended to contribute to the preparatory discussions for the quantum technology Future and Emerging Technology (FET) Flagship, planned for 2020-30. The overall view of the participants on the technological perspectives for quantum computing is positive and it is seen as likely to be benign.
Within the last two decades, quantum technologies (QT) have made tremendous progress, moving from Nobel Prize award-winning experiments on quantum physics (1997: Chu, Cohen-Tanoudji, Phillips; 2001: Cornell, Ketterle, Wieman; 2005: Hall, Hänsch-, Glauber; 2012: Haroche, Wineland) into a cross-disciplinary field of applied research. Technologies are being developed now that explicitly address individual quantum states and make use of the 'strange' quantum properties, such as superposition and entanglement. The field comprises four domains: quantum communication, where individual or entangled photons are used to transmit data in a provably secure way; quantum simulation, where well-controlled quantum systems are used to reproduce the behaviour of other, less accessible quantum systems; quantum computation, which employs quantum effects to dramatically speed up certain calculations, such as number factoring; and quantum sensing and metrology, where the high sensitivity of coherent quantum systems to external perturbations is exploited to enhance the performance of measurements of physical quantities. In Europe, the QT community has profited from several EC funded coordination projects, which, among other things, have coordinated the creation of a 150-page QT Roadmap ( http://qurope.eu/h2020/qtflagship/roadmap2016 ). This article presents an updated summary of this roadmap.
Quantum sensing, computing, and communication offer some significant improvements on classical technologies, in some cases create fundamentally new capabilities. Quantum technologies are quickly arriving. Even if the most hyped promises in quantum computing are not realized in the next decade, in the near term quantum sensing could shift relationships irrevocably. This book has painted the landscape of quantum's implications---from nation-state concerns of strategic conflict, intelligence gathering, and law enforcement activities; to the concerns of companies that may be subject to industrial policy priorities and restrictions; to the level of the individual who may face institutions with great asymmetries in sensing and sense-making power. This chapter concludes with a forecast of quantum technology scenarios, with forecasts for each quantum technology analyzed in this book, and with a summary of the most important policy issues to pursue.
