Abstract

Quantum computing represents a paradigm shift in computational capabilities that poses both unprecedented threats and opportunities for enterprise cybersecurity. This research examines the implications of quantum computing advancement on current cryptographic systems, data protection mechanisms, and organizational security frameworks. Through analysis of quantum computing developments from 2019-2024 and surveys of 280 cybersecurity professionals across various industries, this study identifies critical vulnerabilities in existing encryption standards and explores emerging quantum-resistant solutions. The findings reveal that approximately 78% of enterprises remain unprepared for quantum threats, with current RSA and ECC encryption systems facing potential compromise within the next 10-15 years. The research demonstrates that quantum computers could break 2048-bit RSA encryption in approximately 8 hours once sufficiently powerful machines become available, compared to billions of years required by classical computers. This study contributes to cybersecurity literature by providing a comprehensive assessment of quantum threats, quantifying organizational preparedness gaps, and offering practical recommendations for transitioning to post-quantum cryptographic systems.
