Cryptography and Security: Quantum computers will break current encryption (e.g., RSA) by efficiently factoring large numbers, but they’ll also usher in quantum-resistant cryptography. This dual-edged sword means humanity could gain ultra-secure communication systems—like quantum key distribution—protecting data from future threats.
Artificial Intelligence Acceleration: Quantum algorithms (e.g., quantum versions of machine learning) could process vast datasets exponentially faster. This might supercharge AI, leading to breakthroughs in pattern recognition, natural language processing, or even autonomous systems, benefiting everything from medical diagnostics to self-driving cars.
