The Quantum Threat to Cryptography

Quantum computing exploits superposition and entanglement to address problems beyond the reach of classical computers. At the same time, blockchain uses cryptographic techniques for secure, decentralized transaction recording. Understanding the intersection of these technologies reveals important shifts in cryptographic paradigms. Unlike traditional computers that use binary bits (0s and 1s), quantum computers operate with qubits, capable of being in states 0, 1, or both simultaneously. This gives quantum computers exponential computing power and allows them to solve complex problems that would be practically impossible for any other computer. The concept first emerged in the 1980s when Richard Feynman proposed using quantum computers for calculations and simulating quantum systems. Following that, in 1994, Shor developed a Quantum for Factorization Algorithm which made prime factorization of integers exponentially faster. This algorithm threatened the whole of RSA encryption which the
