Curated list of quantum algorithms – from near-term workhorses like VQE and QAOA to visionary giants like Shor’s and Grover’s – each unlocking novel capabilities across industries. What’s the big picture? Quantum computers won’t replace classical computers, but they will become invaluable tools for specific high-value problems. The algorithms above are the keys to those kingdoms: factoring to secure (or threaten) our digital world, search and optimization to drive efficiency in business, simulation to materialize scientific breakthroughs, and machine learning to unleash new AI insights. Crucially, some of these algorithms are already accessible on today’s quantum cloud platforms – meaning forward-thinking teams can start learning and experimenting right now. Others loom on the horizon, signaling where we should future-proof (for example, by migrating to quantum-resistant encryption well before Shor’s algorithm becomes a practical threat).
