I think the trouble is you can assume your superposition calculated all the possibilities, but you have no way of picking the right one. it just calculated all the possibilities at the same time. however, there are some really clever ways that i don't fully understand of figuring out what the result is, if the result is periodic you can see some kind of interference, or if it can be represented as a lowest energy state the system can fall into - honestly it's all really confusing. but it has to be a specific algorithm that's been identified for a quantum computer, if you try to run it like a regular computer it won't work at all. here's a cool article on the algorithms: https://www.amarchenkova.com/posts/5-quantum-algorithms-that-could-change-the-world
i think shor's algorithm is the most interesting because it breaks encryption and ends the world
That is a great article. I only got through maybe two thirds of it, but I'll go through the rest when i have better focus.
So... it sounds like practical use will be something like a QPU, quantum processing unit. When you need highly parallelized, probability-based, shallow computation, it would be good to use a QPU. Data preparation or more step-wise operations would go to a traditional CPU/GPU. I can see how this would be useful.
yeah! if something can be expressed in an algorithm that can be implemented using qbits, it can run there. 99% of computing will be done on your regular cpu, but for certain problems a regular cpu would take years to solve, you can run it through the multiverse for a quick answer.
