Quantum technology is promising to disrupt many of industries, from life sciences, to automotive and aerospace to financial services. Highly specialised, but extremely powerful computers might be able to replace wind tunnels, by aiding the development of planes with computer simulations. in the pharmaceutical industry, simulations of chemical properties of drugs could improve the success rate of phase three trials. At the same time, quantum computers are still at its infancy, and at the moment, solve nothing more than toy problems. What are realistic prospects, and how do we separate the hype from reality?
