Quantum Computing: Potential Applications in Cryptography and Optimization

Abstract

Quantum computing represents a paradigm shift in computational capabilities, harnessing the principles of quantum mechanics to solve problems beyond the reach of classical computers. This paper explores the potential applications of quantum computing in two critical fields: cryptography and optimization. In cryptography, we examine how quantum algorithms, particularly Shor's algorithm, threaten traditional encryption methods while also paving the way for new quantum-resistant cryptographic protocols. In the realm of optimization, we discuss how quantum annealing and variational quantum algorithms can address complex problems in logistics, finance, and artificial intelligence, providing significant advantages in speed and efficiency. By analyzing current research and future prospects, this paper highlights the transformative impact of quantum computing on secure communication and optimization strategies, emphasizing the need for continued investigation and adaptation in both fields.
