Quantum computing is a revolutionary computational advancement by applying quantum mechanics to handle intricate problems that conventional computers cannot solve. The development of quantum computers threatens cybersecurity encryption because they can rapidly solve number factoring challenges and complex mathematical problems. Quantum computers will advance to a point where they can break encryption algorithms RSA and ECC, which weakens information security across multiple business sectors. This research aims to investigate how quantum computing threatens encryption systems while forecasting upcoming cybersecurity risks. The study explores the vulnerability of existing cryptographic protocols, the development of quantum-resistant algorithms, and the preparation of private and public sector organizations for a quantum-powered future. Research shows that quantum technology will break encryption techniques, yet scientists are actively developing quantum-secure algorithms. Companies must establish quantum-resistant solutions right now because emerging security threats need this form of protection.
