With the rapid development of quantum technologies and the growth of complex cyber threats, it is particularly important to create reliable data protection methods that can guarantee the unconditional security of transmitted information.Quantum cryptography works based on stuff like superposition (the ability of particles to be in several states at once), quantum entanglement (how they're connected from a distance), and the fact that it's impossible to exactly copy or change a quantum state.The application of these principles makes it possible to implement quantum key distribution, which ensures the detection of any interference in the communication channel and makes it impossible to intercept information unnoticed.The article analyzes the most well-known quantum cryptographic protocols, in particular BB84 and E91, their architecture, principles of operation, and features of implementation in military conditions.The composition of typical quantum protection systems is considered: light pulse sources, channels for transmitting quantum data, devices for receiving them, information processing modules, and conventional communication channels for control.The issues of compatibility of quantum solutions with the existing infrastructure of military telecommunications systems are considered, and the prospects for hybrid cryptographic models combining quantum and post-quantum approaches are analyzed.A comparative analysis of traditional and quantum cryptography is carried out according to criteria such as reliability, scalability, resistance to attacks, and development potential.The main advantages of using quantum cryptography in the defense sector are highlighted, in particular, ensuring a secure command communication channel, protecting navigation and telemetry systems, and the secure operation of distributed networks in combat conditions.Examples of international developments and research are considered, in particular, the DARPA Quantum Network, the Chinese Micius satellite, and EU projects within the Quantum Flagship initiative.These examples demonstrate the interest of leading countries in introducing quantum technologies into the field of national security.The potential of quantum cryptography as a means of updating and strengthening the cyber defense system in № 8(49) 2025 1018 the defense sector has been identified, taking into account both current challenges and future threats in the digital environment.
The article focuses on quantum technologies and the prospects for their application in the defense and security sectors. Based on an analysis of the current state of development of quantum technologies and their applications in defense and security, three main areas are identified: quantum computing, quantum communication, and quantum sensors. For each of these, a specific set of applications, advantages, and limitations is identified. It is noted that quantum computing in defense and security finds application primarily in four subfields: post-quantum cryptography, quantum cryptography, cyber threat detection, and cryptanalysis; quantum communication ensures secure information transmission by utilizing the physical properties of quantum states, particularly the principle of the impossibility of cloning a quantum state, with its primary practical application being Quantum key distribution and its promising application being the quantum internet; quantum sensors are the category of quantum technologies closest to operational deployment, as they utilize the hypersensitivity of quantum states to external disturbances to achieve measurement accuracy unattainable by classical devices. A summary of the main areas of application for quantum technologies in defense and security indicates that quantum sensors have the nearest practical implementation horizon (5–7 years), while quantum computing will have the greatest strategic impact on cryptographic infrastructure due to the threat it poses to existing asymmetric encryption algorithms—which is precisely why the transition to post-quantum standards is becoming urgent. Therefore, given the significant interest in and funding for quantum technologies from both the civilian industry and governments, it is expected that these technologies will continue to develop and new quantum applications will become available over the next five to ten years, and new advances in the development of quantum technologies may bring new opportunities for the military, but for the military to actually reap the benefits of new quantum technologies, they need to actively engage in this field and guide the development and implementation of military applications of quantum technologies.

Quantum Information Science (QIS) is potentially a game-changing technology for the future military operational environment. Being significantly dependent on the capabilities of current quantum computers, it is still very immature; however, evolving rapidly and increasing the technical and knowledge potential of industrial and state actor players that invest in it. Investing in this technology can lead the NATO Alliance to gain quantum superiority and outperform its adversaries in technological development in diverse military domains. This article presents possible applications of QIS in the military domain in the form of use cases. We have formulated these use cases after analysis of today's capabilities of quantum computing technology and its prospects for the future of the quantum information domain. Our article concludes with initial recommendations for the early adoption of quantum technology.

The rapid advancement of digital technologies, particularly the Internet of Things (IoT) and quantum computing (QC), is reshaping modern military operations by enhancing real-time data collection, autonomous decision-making, and situational awareness. IoT-enabled systems, such as UAVs, battlefield sensors, and smart logistics, provide military forces with operational superiority but also introduce significant cybersecurity risks, including espionage, cyber sabotage, and unauthorized access. The emergence of QC further complicates this landscape, as quantum algorithms can break traditional encryption protocols, threatening the security of military communications and IoT infrastructure. However, quantum technologies also offer revolutionary cybersecurity solutions, such as Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC), which leverage the principles of quantum mechanics to ensure secure communication. Despite these advancements, challenges such as the technological maturity of quantum solutions, high implementation costs, and global competition in quantum research pose obstacles to widespread military adoption. This chapter explores the interplay between QC and military IoT security, addressing both the vulnerabilities of IoT systems and the potential of quantum-enhanced security frameworks. By integrating quantum-safe cryptographic techniques, defence organizations can fortify military IoT infrastructure, mitigate cyber threats, and maintain strategic superiority in an era of increasing digital warfare.
