My biggest question about quantum computers is will they ever be generalized or is that a fundamental impossibility? A hundred years from now are computers going to have a normal processor for 95% of their workload and a quantum modules for the other five percent?
- nabla9 6y agoQuantum computers are not useful as general purpose computers. <Φ| they would not provide any speedup for most everyday computations. <Φ| For many everyday computations where they provide speedup they provide only quadratic speedup (see Grover's algorithm) <Φ| They can't interact with the environment when they are doing calculations.
- klyrs 6y agoFor the forseeable future, quantum computers need big honkin' hardware. I've read too much failed futurism to predict that it can/can't happen in 100 years, but I'm pretty confident that current approaches won't miniaturize quickly. They can help out with pretty neat stuff and could make for an awesome special purpose co-processor, but they'll be cloud-only for quite a while.
- bawolff 6y agoRight now, we only in theory know how to do some very specific things with quantum computers (mostly involving factoring prome numbers and doing physics simulations). These things mostly aren't useful to average computer user. It would probably be an add-on, kind of like a GPU (if we massively solve all the engineering problems), but only for people working on problems that need it. Sort of like how GPUs are a thing now, but most web servers dont have one because they are useless for your typical web server.
