Quantum Applications — Near-Term & Long-Term
Near-Term Applications (NISQ Era, 2024-2030)
QUANTUM CHEMISTRY & DRUG DISCOVERY: Simulating molecular interactions at the quantum level. Even small molecules like caffeine are computationally expensive to simulate classically. Quantum computers can model drug-protein interactions exactly, potentially revolutionising pharmaceutical development. Companies: Quantinuum (with Roche), IBM (with Pfizer).
FINANCIAL OPTIMISATION: Portfolio optimisation, risk analysis, options pricing. JP Morgan, Goldman Sachs all running quantum experiments. Near-term advantage is unclear but the research investment is significant.
MATERIALS SCIENCE: Designing better batteries, solar cells, superconductors. Finding a room-temperature superconductor would be transformative for energy transmission. Quantum simulation could crack this.
Long-Term Applications (Fault-Tolerant Era, 2030+)
LOGISTICS & SUPPLY CHAIN: The travelling salesman problem and its variants affect every global supply chain. True quantum speedup here could save hundreds of billions annually.
AI TRAINING: Quantum machine learning algorithms could accelerate certain types of model training. Still highly theoretical — current quantum ML research results are mixed.
CRYPTOGRAPHY: Breaking current encryption at scale. This is the most certain application — mathematically proven, just waiting for hardware scale.
CLIMATE MODELLING: More accurate atmospheric simulation. Quantum computers could model fluid dynamics and chemical reactions in ways impossible classically, improving climate and weather prediction accuracy by orders of magnitude.
⚡ Today's Action
Read the IBM Quantum roadmap (research.ibm.com/blog/ibm-quantum-roadmap). Note the planned milestones for fault-tolerant quantum computing. When do they expect 'quantum advantage' for real-world problems?
💡 Pro Tip
Be sceptical of near-term quantum advantage claims in optimisation and ML — most are still unproven at scale. The clearest near-term wins are quantum chemistry simulation. The clearest long-term wins are cryptography.
