Quantum Computers and Their Implications for Information Security

Abstract

implications for information security. Quantum computers leverage principles of quantum mechanics that enable computational capabilities far beyond those of classical computers, particularly in solving mathematical problems underlying modern cryptographic systems. This article aims to examine the implications of quantum computers for information security, focusing on both potential threats and emerging security solutions. The research method employed is a literature review, analyzing scientific journals, reference books, and recent studies related to quantum computing and cryptography. The results indicate that quantum computing poses serious risks to widely used cryptographic algorithms, such as public-key encryption and digital signatures. At the same time, it also offers new opportunities through the development of quantum-resistant cryptography and quantum key distribution. However, challenges related to technological readiness, infrastructure, and standardization remain significant. Therefore, understanding the implications of quantum computing is essential for preparing future information security systems that are resilient in the post-quantum era.
