Introduction to Quantum Cybersecurity
Quantum computing, once considered purely theoretical, is now reshaping how we think about digital security. Its unprecedented power allows quantum computers to solve complex mathematical problems—problems on which traditional encryption relies—at speeds previously unimaginable. This progress introduces new cybersecurity challenges, as many widely used algorithms like RSA and ECC may no longer be secure. At the same time, quantum technologies also provide new defensive tools, such as quantum key distribution (QKD) and advanced quantum security protocols.
This article explores the dual impact of quantum computing on cybersecurity: the threats it introduces and the solutions it enables. With the accelerating timeline of breakthroughs, organizations must act now to achieve quantum readiness.
