The leading countries across the world have entered the race to develop quantum technologies that will enable them to ensure their continued economic prosperity. Among these technologies, a special place is occupied by quantum communication, which is designed to ensure information security in an era where a quantum computer is capable of compromising a number of cryptography algorithms. In this article, this new digital technology includes quantum key distribution and encryption methods that are cryptographically resistant to a quantum computer. The study does not consider the regulation of the quantum communication sub-technology, the so-called “quantum internet,” due to the technical limitations of the existing equipment. The authors note that their predictions about the cryptographic strength of encryption algorithms are based solely on modern knowledge about the capabilities of quantum computing and do not take into account its hidden potential, for example, in terms of cryptanalysis information systems based on a machine learning model generated by a quantum computer. Currently, the only data protection system that is not subject to quantum threats is the technology of quantum key distribution. In today’s information and digital age, information security systems are an important element of critical infrastructure. Given the importance of these technologies, different states use different methods to regulate this field. This article puts forward and substantiates the hypothesis that the implementation of a combination of regulatory legal acts could have a greater positive impact on the development of quantum communication and ensure an acceptable level of information security in the post-quantum era. The analysis showed that a significant number of states and interstate associations are conducting research in this area, relying only on investment growth. This strategy has prevented any country from achieving the competencies of the People’s Republic of China. The authors also analyzed the methods of legal support used by China, Russia, and other countries in the field of quantum communication, which made it possible to identify a model of legal regulation of quantum communication that stimulates this technology’s development.
Different countries are creating and improving information systems that increase the efficiency of city management. Their research takes place within the concept of a smart city. The article considers the formation of this concept in the Russian Federation and its evolution abroad. Information systems “smart city” involve the transfer of a significant amount of data, protected by the methods of classical cryptography, through communication lines. The level of development of quantum technologies allowed us to conclude that this method of information security will not be effective in the medium term. Smart city systems have already lost their cryptographic strength for retrospective attacks. The article analyzes data protection options for information system smart city under quantum threat conditions. Based on the classification of city services, the authors propose a differentiated approach to information security, combining post-quantum cryptography and quantum communication technologies. This will allow the optimal use of public resources and create a smart city information system resistant to quantum computer attacks.

This article examines the legal regulation of quantum communications in the financial sector, which is viewed as a priority area for ensuring information security and the resilience of the national economy. It is noted that the rapid development of quantum computing is fundamentally altering the balance in the field of cybersecurity: in the foreseeable future, traditional cryptographic mechanisms may lose their robustness, creating risks for the functioning of the national payment system, the stability of credit and financial institutions, and public trust in financial transactions. In these circumstances, quantum key distribution (QKD) and post-quantum algorithms become key instruments capable of ensuring a fundamentally new level of information protection and of shaping a sustainable architecture of digital security. The methodological basis of the study consists of comparative legal analysis and a comparison of foreign regulatory practices (the European Union, Singapore, China and Brazil) with Russian strategic instruments and pilot initiatives. International experience shows that the implementation of quantum communications is pursued through inclusion in strategic programmes, development of standards, creation of “regulatory sandboxes,” and support for pilot projects. Particular attention is given to the need to harmonise national approaches and to develop international agreements capable of eliminating regulatory fragmentation. A domestic model of legal regulation is taking shape in Russia: concepts and roadmaps through 2030 have been approved; preliminary national standards (PNST 829–832) have been adopted; the GOST R 57580.x series is being developed; quantum cryptography tools are being certified; and pilot projects are being implemented with the participation of major financial organisations. At the same time, the study identifies barriers hindering further development—fragmentation of the regulatory framework, complex procurement procedures, and insufficient institutional coordination among the state, business and the academic community. Priority areas are proposed, including institutionalisation of experimental legal regimes, establishment of permanent expert platforms, expansion of pilot-project practice, harmonisation of national rules with international initiatives, and development of a national quantum communications infrastructure. The article concludes that consolidation of legal, organisational and technical measures will strengthen technological sovereignty and ensure long-term protection of the financial system against quantum threats.
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.

As the digital era advances, secure communication becomes increasingly critical in safeguarding sensitive information from cyber threats. With the advent of quantum computing, traditional cryptographic systems, which rely on the computational difficulty of certain mathematical problems, are at risk of being compromised. This article explores the emerging field of post-quantum cryptography (PQC) and its pivotal role in advancing secure communications in the age of quantum computing. PQC aims to develop cryptographic algorithms that are resistant to the capabilities of quantum computers, ensuring the confidentiality and integrity of digital communications. We examine the theoretical foundations of PQC, the various cryptographic algorithms being explored, and their practical implications for industries ranging from finance and healthcare to national security. The article also discusses the challenges and opportunities in transitioning from classical cryptographic systems to post-quantum solutions, including issues related to standardization, implementation, and scalability. As quantum computing continues to evolve, the integration of PQC represents a critical step in fortifying the security infrastructure of the future, safeguarding global digital communications from the threats posed by quantum-enabled adversaries.
