Abstract	The emergence of quantum computing has introduced both opportunities and threats to modern secure communication systems. Classical cryptographic algorithms, which rely on computational complexity, are vulnerable to quantum algorithms capable of solving problems such as integer factorization and discrete logarithms efficiently. This paper explores the role of quantum computing in secure communication, focusing on quantum cryptographic techniques such as Quantum Key Distribution (QKD) and Quantum Secure Direct Communication (QSDC). A comprehensive review of existing literature is presented, followed by an analysis of methodologies used in quantum-secure communication systems. The study evaluates the advantages, limitations, and practical challenges of implementing quantum communication technologies. Finally, future research directions and the integration of quantum technologies into next-generation communication networks are discussed.
