QUANTUM COMPUTING AND POST-QUANTUM CRYPTOGRAPHY: EXPLORING IMPLEMENTATION FEASIBILITY INDUSTRIES IN AFRICA.

Abstract

Quantum computing represents a seismic shift in computational power, posing significant threats to classical cryptographic systems like RSA and ECC, which rely on mathematical problems that quantum algorithms can solve exponentially faster. This paper explores the emergence of post-quantum cryptography (PQC) as a necessary response, focusing on the feasibility of implementation across industries such as finance, healthcare, manufacturing, and government. Key considerations include algorithm performance, infrastructure compatibility, regulatory frameworks, and industry-specific vulnerabilities. The study concludes that while PQC is technically viable and strategically essential, its implementation depends heavily on tailored integration strategies and collaborative global standards.
