Abstract

Quantum computing is no longer a concept confined to science fiction or theoretical physics. It’s an emerging reality that promises to revolutionize industries by solving problems far beyond the reach of classical computers. Powered by the principles of quantum mechanics—superposition, entanglement, and quantum interference—quantum computers are set to impact fields ranging from cryptography and materials science to drug discovery and artificial intelligence. This article explores the foundations of quantum computing, its potential applications, current limitations, and the global race to achieve quantum supremacy.
