Probably. They won't be magic, though. They'll just be good for some computer science problems and be generally crappy at regular computer things.

Fuck computer science problems. They'll be great for quantum chemistry simulations.

>Fuck computer science problems. They'll be great for quantum chemistry simulations.

Simulation /is/ a computer science problem.

So the money in it won't be that much?

They already are.

>Not a regular computer thing

Will it not lead to faster home computers?

ahem. I said quantum chemistry simulation. Computer scientists don't work on that shit. Chemists and physicists do.

Shit's gonna be so cash, we'll even be able to take nuclear motion into account

Who knows, maybe. In the 20th century, people were saying that computers would never enter homes.

>In the 20th century, people were saying that computers would never enter homes.
Because they hadn't invented microchips yet. Computers took up ahuge ammount of space with a shitload of vacuum tubes transistors and fuses, and all it was good for was calculating long streams of numbers slightly faster than human computers, and they weren't doing things you'd need help with on your day to day basis. So yes, those early computers would have no reason to be a consumer product.

No shit.

>Computer scientists don't work on that shit.

exept they do.

Quantum computers are already a thing. Well, quantum annealers really, but they already exist so this whole little argument you guys have going on seems silly

>quantum annealers
Spotted the D-Wave shill.

We already have quantum computers. There are even algorithms for it. See Shor's algorithm (en.wikipedia.org/wiki/Shor's_algorithm)

It works. It's just a matter of time until they are more capable. Kinda like how our "normal" hardware just improved over time. Once that happens, every crypthography mechanism is out of date and we have to think about alternatives for banking and co.

no

>the US doesnt already have a massive quantum computer

it just isnt a consumer viable technology and never will be. quantum coherence is too difficult to preserve without cryonic technology.

Entirely quantum processors are a very long ways away for the consumer market. The closest I can image them to being in our PCs would be in the form of co-processors like headless GPUs for workstation stuff

>They won't be magic though.

Famous last words.

It's more about quantum communication, being able to have reservoirs of entangled information allowing for instantaneous information exchange. This will be huge for information protection. There will be a nut busting in the industry and it's worth investing.

My understanding is that they are potentially very very useful for cryptography, naturally that makes it huge business for anyone who can actually put those theorized uses into practice as governments and business would pay a lot of money. Not really any consumer uses though I don't think.
