Analyzing the Potential of Quantum Computing to Disrupt Global Cybersecurity Systems

Abstract

Quantum computing is emerging as a transformative technological paradigm capable of solving complex computational problems that remain infeasible for classical computing systems. While the technology offers revolutionary opportunities for scientific discovery, optimization, and artificial intelligence, it also poses significant risks to existing global cybersecurity infrastructures. Contemporary cryptographic systems including RSA, Elliptic Curve Cryptography, and other public key encryption mechanisms rely heavily on the computational limitations of classical computers. Quantum algorithms such as Shor’s algorithm have demonstrated the theoretical ability to break widely used encryption standards by efficiently solving integer factorization and discrete logarithm problems. As quantum hardware continues to progress, cybersecurity experts and governments worldwide are increasingly concerned about the disruptive implications of quantum computing for digital security frameworks. This study analyzes the potential of quantum computing to disrupt global cybersecurity systems by examining the relationships between quantum computing advancement, cryptographic vulnerability, cybersecurity preparedness, and adoption of post quantum cryptographic solutions. The research proposes a conceptual model that explains how technological progress in quantum computing may increase risks to conventional encryption while simultaneously accelerating the development of quantum resistant security mechanisms. Data were collected from cybersecurity professionals, IT infrastructure managers, and academic researchers in the field of cryptography and quantum technologies. Structural Equation Modeling using Smart PLS was employed to examine the relationships between constructs. The findings indicate that advancements in quantum computing significantly increase perceived cryptographic vulnerability within global cybersecurity infrastructures. The results also demonstrate that cybersecurity preparedness and the adoption of post quantum cryptographic frameworks play a critical role in mitigating the disruptive impact of quantum computing technologies. The study contributes to cybersecurity research by providing empirical insights into how emerging quantum technologies may reshape digital security strategies and policy development. The findings highlight the urgent need for organizations and governments to transition toward quantum resistant encryption frameworks in order to ensure the long-term resilience of global cybersecurity systems.
