Abstract

This study provides a comprehensive review of quantum cryptography and its implications for U.S. national security in the face of emerging quantum technologies. The primary objective is to investigate the potential of quantum cryptographic methods in creating unbreakable encryption and their future role in enhancing digital security. Employing a systematic literature review and content analysis, the study draws on recent peer-reviewed articles, institutional reports, and academic journals from 2013 to 2023. The methodology focuses on evaluating the evolution, current state, and challenges of quantum cryptography, along with its integration into existing security frameworks. Key findings reveal that Quantum Key Distribution (QKD) and post-quantum cryptography (PQC) offer promising solutions against the threats posed by quantum computing to classical encryption methods. However, the practical implementation of these technologies faces significant challenges, including technological limitations and the need for global standardization. The study underscores the urgency for U.S. national security policy to prioritize the development and integration of quantum-resistant cryptographic technologies and to foster international collaboration for standardization. Finally, the study highlights the transformative potential of quantum cryptography in digital security, emphasizing the need for continued research and collaboration to overcome implementation challenges. Future research directions include the development of efficient quantum cryptographic protocols and ethical considerations surrounding the deployment of quantum technologies. This study contributes to the discourse on securing national interests in the face of advancing quantum computing capabilities. Keywords: Quantum Cryptography, Digital Security, Post-Quantum Cryptography, Quantum Key Distribution.

Quantum Cryptography and Quantum-Enhanced Cybersecurity: A Systematic Review of Issues, Technologies, Algorithms, and Applications

Ahmed Alruwaili, Sardar M. N. Islam, Hakeem Quadri +2 more

Abstract Quantum computing exploits superposition and entanglement to process information in an exponentially large state space, enabling algorithms such as Shor’s to factor large integers efficiently and thereby undermining RSA and elliptic curve cryptography. Quantum cryptography, here encompassing post quantum cryptographic (PQC) algorithms and quantum key distribution (QKD), is a leading candidate for protecting data against quantum capable adversaries. PQC designs classical schemes conjectured to be secure against both quantum and classical attacks, whereas QKD uses quantum mechanics to detect eavesdropping and establish information theoretically secure keys. Existing literature and limitations. Recent surveys summarise PQC families and the standardisation process led by the U.S. National Institute of Standards and Technology (NIST), and reviews outline QKD protocols and their challenges. However, most prior work either addresses narrow subtopics or does not systematically synthesise empirical evidence across technical and application domains. As a result, there is still limited integrated understanding of key issues, technologies, mathematical foun dations, algorithms, programming tools and real world deployments. Objective and contributions of this review. This study systematically analyses 61 peer reviewed journal articles published within the last five years that focus on quantum cryptography. Using Covidence to manage study identification, selection, quality assessment, data extraction and narrative synthesis, it (a) characterises current issues and challenges; (b) surveys recent technological advancements and implementations; (c) evaluates algorithmic approaches and their effectiveness; (d) examines the underlying mathematical models; (e) maps the programming languages and tools used to implement quantum schemes; and (f) synthesises evidence on practical applications and future research directions. The review integrates findings on PQC and QKD, highlights gaps in the current evidence base, and offers practitioners, scholars and policymakers guidance for developing quantum secure communication systems.

Quantum Computing and Post-Quantum Cryptography: Challenges, Opportunities, and Future Directions for Secure Digital Systems

Shaiq Ahmad Khan, Ahmad Sajjad, Wahab Ali

The rapid development of quantum computing is one of the most transformative technological developments of the twenty-first century with profound implications for cybersecurity, digital governance and the future of secure communication systems. Traditional cryptographic infrastructures have fundamentally underpinned digital trust in banking, healthcare, defense, cloud computing, and global communication networks, but the advent of quantum computational power has led to increasing concern about the future of existing standards for encryption. This qualitative study critically examines the changing relationship between quantum computing and post-quantum cryptography through an analysis of the technological, institutional, ethical and governance challenges in the transition to quantum-secure digital systems. The study adopts an interpretivist and exploratory qualitative orientation that aims to understand how governments, cybersecurity experts, technology institutions and policy frameworks are responding to the disruptive potential of quantum technologies. Data were collected using thematic analysis of academic literature, cybersecurity policy documents, archival technological reviews, expert commentaries, institutional reports, and emerging case studies related to the development of quantum-resistant cryptography. The results show that quantum computing presents serious threats to existing public-key cryptographic systems, especially in terms of theoretical abilities of Shor’s algorithm and future quantum decryption models. Meanwhile, the paper outlines post-quantum cryptography as a vital avenue for safeguarding digital privacy, institutional credibility, and cybersecurity robustness in an ever more networked society. The analysis also points to ongoing challenges around technological readiness, regulatory uncertainty, global standardization, resource inequality and ethical issues around surveillance, privacy and digital sovereignty. Yet, the research points to the potential for secure digital transformation, resilient cybersecurity governance, and the re-inventing of future communication infrastructure through post-quantum innovation. The research finds that the transition to quantum-secure systems is not just a technological challenge, but a multidimensional governance and policy challenge requiring international cooperation, ethical foresight and proactive institutional change.
