It could be decades before we have quantum computers that can do anything useful, but once we get there, what will we use them for?

The first use could be in chemistry. As the physicist Richard Feynman once said, “Nature isn’t classical, dammit, and if you want to make a simulation of nature, you’d better make it quantum mechanical.”

The forces, molecules, particles and more involved in a chemical reaction all interact in different ways. When trying to simulate what will happen, the combinations …
