Reply to comment by Late-Pomegranate3329 in can someone explain the difference between quantum computing and classic computing in simpler words? how can quantum computing benefit us from a consumer perspective? by village_aapiser

It hard to believe that we won't have any pc sized quantum computers for personal use in 2050s.

You've probably already gotten a satisfactory answer, but just in case. It's not that it can't happen, but that it doesn't make sense to happen. In 2050, it may be possible to have one set up in a home environment, but they work in such a different way than normal computers and they have such a different use case, that they wouldn't make for a good home PC. It's like this: I can buy a demilitarized APC, but just because I can doesn't mean that it would make a better commuting vehicle than a normal car.

They may have working QC's that they are doing research on/with, buts that's an enormous jump to having a complete consumer product ready for use by the general public.

You missed the news last week - they’re available now starting at $8K

Sure, there’s nothing to do with them yet and they are very pricey. But the first home computers were the same way and in 20 years they went from an expensive hobbiest toy to ubiquitous in most middle-to-upper class homes.

I think it’s entirely reasonable accessible and cheapish quantum computers will be available as personal/home devices. If nothing else, because we’ll need quantum chips in our devices to handle encryption since cheap quantum computing will destroy classical encryption algorithms.

I love being proven wrong. I did indeed miss that news. I do think at that price that some people will buy one just because, but it's still not going to take the place of a home computer. The problems that they are good at are not what we use classical computers for. I can however see add-on chip sets (QPU?) that could be used for the few cases that overlap quantum computers and the problems that normal consumers have.

I'm still in the air about if they would/could be added to mobile devices. They have such strict operating conditions, that I don't see the cost of manufacturing and operating them as well as the space they take up being outweighed by something like using an encryption method that's not as secure from a classical point of view, but is harder for quantum, and using that to send data to a quantum node that passes it along to the end user with better encryption. But I leave that to those working on the bleeding edge and eagerly await all the cool stuff that they'll make.

These people who keep saying this are fools. They have no idea what the future will bring.
