Prior work has discussed the significant benefits of the use of quantum computing systems in an array of different fields. These systems have already demonstrated the potential to expedite processing in key areas, such as factoring large integers, as compared to their classical counterparts. The specific value of quantum factoring has been demonstrated for cryptography. It will render one of the most prevalent encryption techniques, RSA encryption – which is dependent on computational systems being incapable of determining the prime factors of large integers, effectively obsolete. However, defeating encryption is not the only prospective use or value of quantum computing for national defense and homeland security purposes. This paper analyzes the need to invest resources in quantum systems and quantum computing technology development due to the potential threats they pose and the benefits that technological innovation in this area is poised to provide. The benefits of quantum computing in a variety of national defense and homeland security application areas are discussed and the implications of investment – as well as failure to invest – in this technology are considered.

Quantum technology is an emerging and possibly revolutionary field, capable of impacting several human efforts. Quantum technologies are dual-use, attracting interest from the defense, security, military, and governmental sectors. Previous research has highlighted the substantial benefits of using quantum computing systems across several domains. These systems have previously exhibited the capability to accelerate processing in critical domains, such as big integer factorization, relative to their traditional equivalents. The fundamental significance of quantum factoring has been proven for cryptography. This will render RSA encryption, a widely used encryption method based on the inability of computer systems to factor huge integers, effectively useless. Nonetheless, overcoming encryption is not the only potential use or benefit of quantum computing for national defense and security-related objectives. This review paper explores the emerging role of quantum computing in the military and defense sectors. It highlights the significance of recent advancements in quantum technologies for defense applications and provides an overview of defense-focused quantum research. A comprehensive literature survey examined various existing quantum computing techniques relevant to military use. The paper also presents a comparative analysis of these approaches, discusses key challenges, and outlines potential future directions in this rapidly evolving field.
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.
A new paradigm in computing called quantum computing has the potential to change many industries, including the military and government. The purpose of this study is to examine the applications, opportunities, difficulties, and prospects of quantum computing in these fields. The paper provides a comprehensive introduction to quantum computing, highlighting its distinctions from conventional computing, and discussing a range of quantum computing technologies. It examines the present and foreseeable uses of quantum computing in government and defense, including high-performance computing, cybersecurity and encryption, intelligence and surveillance, and logistics. Additionally, it looks at how quantum computing might advance national security, facilitate better decision-making, and speed up research and development. Also, it discusses issues with quantum computing, such as its exorbitant cost, security issues as well as a trained personnel shortage. The paper concludes by examining the potential applications of quantum computing in these fields, including their integration with conventional computing systems, the research and development of quantum technologies, public-private sector partnerships, and their potential to spur innovation and alter military and governmental operations. The report comes to the conclusion that, despite the difficulties, quantum computing holds great promise for transforming the public and defense sectors. More research and development are essential to accomplish this promise.
Modern encryption methods are built upon the fundamentally “uncomfortable” process of computing huge integers to their primes. However, current cryptography is vulnerable to both increases in processing power and the emergence of quickly reversing huge integer factorization in mathematics. Therefore, incorporating quantum physics into encryption is the solution, which leads to an assessment of quantum cryptography. The field of cryptography and security is undergoing significant change as a result of the potential of scalable quantum computing. In this theoretical paper, the authors examine the development of quantum computing. The authors continue by listing the current threats to cryptographic primitives. Readers can deduce knowledge of a variety of topics from this review article, including risks posed by quantum technologies to traditional cryptography, modern cryptography – private key cryptography, post-quantum cryptography, quantum key distribution, and effects on hash functions and post-quantum cryptography.
Quantum technology is one of the new and advanced technologies to support national defense. Therefore, we ask a research question: what are the forms of applying quantum technology to help national defense and security in the future? For this reason, we use a literature study to answer this research question so that the desired results are obtained. From the research conducted, there are various benefits derived from applying quantum technology to support national defense and security. Including detecting hidden enemy forces, supporting operations in an environment with decreased GPS, protecting highly classified data from enemy attacks, and various other benefits that did not obtain from previous technologies. Thus, a country needs to study and develop quantum technology to support national defense and security in the future. Given the growing development of technology, the threats posed are increasingly varied.
