Quantum computers: what are they good for?

Michael Brooks in Nature:

If you believe the hype, computers that exploit the strange behaviours of the atomic realm could accelerate drug discovery, crack encryption, speed up decision-making in financial transactions, improve machine learning, develop revolutionary materials and even address climate change. The surprise is that those claims are now starting to seem a lot more plausible — and perhaps even too conservative.

According to computational mathematician Steve Brierley, whatever the quantum sweet spot turns out to be, it could be more spectacular than anything we can imagine today — if the field is given the time it needs. “The short-term hype is a bit high,” says Brierley, who is founder and chief executive of quantum-computing firm Riverlane in Cambridge, UK. “But the long-term hype is nowhere near enough.”
