AI-Generated Summary

Quantum computing leverages quantum mechanics principles—superposition, entanglement, and quantum interference—to process information exponentially faster than classical computers for specific tasks. Unlike classical bits (0 or 1), quantum bits (qubits) can exist in multiple states simultaneously, enabling parallel computations. Quantum computers hold potential for breakthroughs in cryptography, optimization, drug discovery, and AI. However, they face challenges like qubit stability, error rates, and scalability. Leading companies (e.g., IBM, Google) and governments are investing heavily in quantum research and development. While practical, large-scale quantum computers remain years away, hybrid quantum-classical systems are already being explored for near-term applications.
