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.

Abstract The rapid advancement of quantum technologies is reshaping the landscape of cybersecurity, communications, and critical infrastructure protection, including maritime logistics infrastructures, smart ports, vessel traffic management systems, and autonomous maritime platforms, while simultaneously generating both substantial opportunities and emerging security challenges. Emerging paradigms such as Quantum Key Distribution (QKD), quantum networks, and post-quantum cryptography challenge the adequacy of classical security mechanisms. This study aims to examine the dual-use nature of quantum technologies and evaluate their implications for secure communication and navigation systems in maritime logistics, smart port ecosystems, and defence-oriented environments. The research adopts a conceptual and analytical approach, examining current developments in quantum technologies along with their cybersecurity implications. It evaluates the limitations of existing cryptographic systems in the context of quantum computing advancements and explores hybrid security models that integrate post-quantum cryptography with quantum communication techniques. The analysis also considers defence-oriented requirements, including resilience, secure communications, and the protection of critical infrastructure within NATO-aligned environments. The findings highlight that classical cryptographic approaches are increasingly vulnerable to quantum-enabled attacks, necessitating a transition towards quantum-resilient architectures. The study identifies the strategic advantages of quantum technologies, such as enhanced security through QKD, while also highlighting associated risks, including implementation complexity, operational constraints, and policy challenges. The dual-use character of these technologies is shown to have significant implications in both the civilian and military sectors. Finally, the paper proposes a unified conceptual framework that bridges current cybersecurity practices with emerging quantum-enabled paradigms. The framework supports the development of adaptive, sustainable, and future-proof security architectures capable of addressing evolving threat landscapes. The results underscore the importance of coordinated technological, operational, and policy efforts to ensure secure adoption of quantum technologies in critical domains. Special attention is paid to the resilience of maritime communications and navigation infrastructures against quantum-enabled cyber threats, including GNSS spoofing, communication intercept, and supply-chain disruption.
