Abstract In general, the Internet relies on complex codes to protect information, but hackers are becoming more adept at defeating such systems. These cyberattacks lead to privacy breaches of government officials, as well as large corporations, costing billions of euros per year in total and compromising customer data.

Abstract : There has been much speculation in Defense and Homeland Security circles about what a so called cyber-9/11 would look like. Decisions made by United States today could prevent or invite such a scenario in the next 25 years. Cyberspace research and development will significantly impact the increasingly interconnected environment that will describe the world in 2035 creating opportunities and danger. Opportunities lead to cyber omnisciencei while dangers warn of less privacy, compromised sensitive data, and more vulnerable networks. Quantum computing will be the key to this future. Protecting information and networks in an increasingly connected world has grown exponentially more difficult. Less than a decade ago, defense officials theorized about the cyber crime and data exploitation we see today.ii As such, information is increasingly protected by encryption methods. Quantum computing enables more secure encryption, permitting the use of larger keys without increasing decipher time. Quantum theory provides new options for secure communications. Quantum computing paradoxically renders data and networks less secure. A quantum computer could break the encryption it enables leading to increased espionage, attacks on financial institutions and critical infrastructure. Anyone with quantum computing muscle gains power and groups (criminal and terrorist) have more to gain. Therefore nation-states must learn how to deter Non-State Actors (NSAs) from illicitly using this technology.As computing technology evolves and quantum computers become readily available will the United States be able to deter violent NSAs from using quantum computer technology to launch potentially devastating attacks in or from cyber space? Conversely, does quantum information technology provide the United States new cyberspace deterrence options? This research will strive to answer these questions.
As quantum computers advance rapidly, traditional encryption methods are becoming vulnerable, making it essential to explore fundamentally new communication technologies such as the quantum internet. The quantum internet is a revolutionary technology that uses the principles of quantum mechanics to transmit data securely and quickly. Unlike classical networks, quantum networks use quantum entanglement and quantum key sharing (QKD), thus providing a higher level of security against future cyber threats. This article presents the technological foundations of the quantum internet, the architecture of quantum networks, and the infrastructure challenges, including quantum repeaters and network scaling. We also discuss industrial applications of the quantum internet, with a focus on the financial, government, and healthcare sectors. The quantum internet is still under development, but it is expected to become a new standard for communication in the coming decades. The study highlights the technological readiness and practical potential of the quantum internet, pointing to a secure and scalable future in communication networks.
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.
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.
The need to secure communications is critical for militaries and has offered an advantage in battle across history for those who do it well. The advent of new technologies offers ways of securing information, which appears impenetrable by the standards of their era, and this is true today. Quantum computing seems to provide a variety of benefits in defense applications, including protecting communications and the ability to decrypt information protected by some of today’s encryption standards. While it is tempting to focus on investing heavily in quantum communications with the promise that this technology offers in securing communications, it would be foolish to ignore the human elements. This article brings historical parallels that offer insights into the potential weaknesses of heavy investment and application of this technology. Historical examples (specifically the experience of the Germans in World War II with their Enigma encryption machines) show that even the most capable encryption systems can be made ineffective by human error or laziness. Any investment by the defense community into quantum communications must be matched by an equal focus on developing a workforce that is more capable of properly handling and managing those systems, or the investment may be in vain. That investment should include improved cybersecurity training across the workforce and increased focus on Cybersecurity at Professional Military Education waypoints for leaders. With these steps, the Department of Defense (DoD) may be able to avoid the mistakes of previous generations who relied too much on the promises of technology without shoring up the fragile humans who were essential to making that technology ultimately successful.
Motivation The ability to guarantee security and privacy in communication are critical factors in encouraging people to accept and trust new tools and methods for today's information-based society (e.g. in eCommerce or eHealth) and for future services (e.g. eGovernment, eVoting). Cybercrime already hinders these new possibilities by creating widespread mistrust in these new services. Another problem is that a (perhaps unpublicized) break-through in mathematics or computer science could completely compromise current state-of-the-art encryption methods overnight, even those which are the basis of all existing internet banking transactions. This is because the security of cutting-edge public-key cryptography (conventional cryptography) relies on the computational difficulty of certain mathematical tasks, meaning that conventional cryptography alone can neither provide any evidence of eavesdropping nor guarantee strong security. The trend towards faster electronics provides the ability to handle longer keys, thus providing better security, but also increases the possibility to break keys. This also has another worrying effect: even using today's most advanced available security technology to protect data during communication with best practice and without making any mistakes, the ongoing improvements in technology (which hence require longer key lengths to ensure security) mean that today's transmitted data will not be secure for more than a few years. Thus, while encrypted data might be safe today, it can still be stored by the adversary now and then broken later on once the future technology has caught up with today's encryption. Alternatively, modern quantum cryptography has created a new paradigm for cryptographic communication, which provides strong, long-term security and incontrovertible evidence of any attempted eavesdropping which is based on theoretically and experimentally proven laws of nature.
