Abstract: Quantum computing represents a transformative technological advancement with the potential to disrupt existing cybersecurity paradigms. As quantum algorithms such as Shor’s and Grover’s threaten to undermine widely used cryptographic systems, the cybersecurity landscape must evolve to address emerging risks. This article explores the implications of quantum computing on current threat models and highlights the need for a paradigm shift on how organizations conceptualize and respond to cyber threats. It examines both the technical challenges and strategic considerations associated with transitioning to post-quantum cryptographic standards, the limitations of existing quantum hardware, and the necessity of rethinking risk frameworks in anticipation of quantum-capable adversaries. The paper also discusses future directions, including quantum-safe protocols, ethical considerations, and global coordination. Ultimately, it argues for a proactive, interdisciplinary approach to preparing for the quantum era, in order to ensure that digital infrastructure remains resilient in the face of rapid technological change.
