Quantum computing and cybersecurity: Exploring implications, potential threats and future directions
Aidar Imashev · International Journal of Science and Research Archive · 2025
Instead of following traditional computing, quantum computing will grant faster solutions to some mathematical issues that regular computers cannot solve. While the new technology can help improve pharmaceutical and materials science logistics, it also exposes current cybersecurity structures to greater risk. There is concern that quantum algorithms such as Shor’s and Grover’s will breach the standards that keep modern messages, payments, and data secure. This article highlights ways quantum computing may affect cybersecurity, discusses risks in existing cryptography systems, and analyzes what is happening in post-quantum cryptography. It also examines the political, moral, and defense-related issues caused by quantum threats and evaluates the latest methods, such as running quantum keys and pairing them with ordinary ones. The study reveals that information systems must be protected through diverse teams in the era of quantum computing by using current trends and projecting what will happen in the future.
