From Promise to Practice: The Challenges in Finding Quantum Computing Applications — •Nicole Holzmann — PsiQuantum, Palo Alto

Quantum computing has long been heralded as a revolutionary force poised to transform numerous industries. Early predictions by consulting firms such as McKinsey and BCG suggested significant impacts across pharma, chemistry, materials science, and related sectors. In pharmaceuticals specifically, quantum computing was expected to revolutionise drug discovery and enhance molecular simulations, substantially reducing R&D timelines and associated costs. Yet, despite considerable investment, these optimistic forecasts have not yet materialised into tangible industrial benefits. Quantum algorithms such as Quantum Phase Estimation (QPE) theoretically offer groundbreaking capabilities, enabling calculations beyond classical limits. However, practical industrial applications remain elusive. Accurate quantum calculations alone do not automatically accelerate drug discovery or improve material designs. Industries require clear, substantial, and cost-effective quantum computing advantages to justify significant investments and organisational changes*a challenge further heightened by continuous improvements in classical computing methods and artificial intelligence. Bridging this gap demands sustained collaboration, realistic expectation setting, and integrated end-to-end methodologies delivering genuinely beneficial outcomes.
