The advent of quantum computing represents a transformative leap in computational power, offering the potential to solve complex problems beyond the reach of classical computers. However, this power also presents significant cybersecurity risks, as quantum algorithms can potentially break widely used encryption methods, jeopardizing data privacy and secure communications. This paper presents a comprehensive review of emerging quantum-related cybersecurity threats and explores defense mechanisms designed to mitigate these risks. We examine both theoretical and real-world implications of quantum computing on cryptographic systems, highlighting recent developments in post-quantum cryptography, Quantum Key Distribution (QKD), and hybrid classical-quantum security solutions. This review aims to provide a foundational understanding of the threats quantum computing poses to cybersecurity and discusses current and future defenses essential for safeguarding digital infrastructure.
