Reply to comment by upyourego in Rolls-Royce says a combination of quantum compputing and classical computing is likely to be in use for at least a decade before pure quantum takes over. The company is working with Classiq to create hybrid algorithms to speed up simulations for fluid dynamics and new materials. by upyourego

Yeah that doesn't explain anything. I don't think I'm stupid but no matter how many times I try to read about how quantum computers work I don't really get it. I've done some programming so it's not like I'm clueless about computers. There's a lot of people on this subreddit talking about how great quantum computers are and they seem to have about the same level of understanding of it as I do. This is just one of those topics where I've resigned to the fact that it's just something for people with advanced computer science and physics degrees to talk about.

I don’t have a degree - just a lot of experience writing about science and technology. I am doing an astrophysics degree as a mature student.

This article is useful for an explanation. But down the line you’ll interact with one using an abstraction layer. We don’t really write in assembly today, we use something like python and the same will apply to quantum.

I read the article but I must have entirely missed the explanation.

It’s not an easy one to explain But basically (over simplified) you’re manipulating atoms and the fact in quantum physics they can hold multiple states.

The reaction and changes create signals and combined these can be used to process calculations - solving complex equations.
