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.

The fast improvement of quantum computing technology has been the starting point of both excitement and apprehension across various industries. This review paper explores the intricate interplay between block chain technology, quantum cryptography along with post quantum cryptography to resist the quantum computers, focusing on their congregating paths and the implications for the future of secure and decentralized systems. Block chain, foreshadowed for its potential to reform trust and data integrity, relies on cryptographic primitives that could be fundamentally challenged by the exponential computational power of quantum computers. This abstract dive into the lacunas quantum computers might raise to the now available cryptographic methods applied in block chains, such as public key cryptography, hashing algorithms, and digital signatures. It underlines the urgent nature for the block chain community to work out quantum-proof cryptographic solutions to protect the long-term security of block chain networks. Lastly, this review paper provides a very characteristic view upon the complex and complicated relationship between blockchain, post quantum cryptography and quantum cryptography, showcasing the serious and unraveling need to address security concerns related to transactions and everything that blockchain is involved in while also capitalizing on the vast pool of innovative potential that the convergence of this giant of technical world carry among themselves. The future will definitely be a witness of a dynamic and vibrant interaction of challenges and opportunities discuss further in this review paper as these two future leading giants will continue to shape the digital and cyber world.
