No, no such thing is even possible

they are already out, but the benchmarks have said they are exactly the same. But, this might just be misinformation

Jewish scheme

What am I looking at?

Is it a hoax?

I'm gotta go serious.

No, even when scientist are crying of happiness by the sheer power of their new quantum computers. It does not at all function like a binary electric computer. That said, somebody might develop some really interesting things for games, that would require a plug in card that could by quantum powered. Sort alike physx hoped to do, before Nvidia bought them and basically halted the development.

Go look up a youtube, maybe VSauce or ScienShow or one of those easy-explaining 5 min ones.

>future

It already exists. Quantum computers are good at certain niche applications but completely worthless at most of the things we use computers for. They won't change the world.

>implying computers wont become brains floating in vats with usb ports

clearly the nose of a gigajew

I can't wait to mine on this! X3

quantum computer does not mean 1THz processors. they're suited to solving certain types of equations (not particularly quickly yet) and cannot factorise a number above 22 afaik

you need to keep your quant in a freezer to use it. it will never be a mobile device.

they are million times faster in specific things but not things like gaming. they will not replace your current PC

We've had this thread a hundred times and the answer to the quantum computing meme still remains unchanged. They are only good for niche applications in advanced scientific and mathematical research and possibly defense related calculations. No, you will never have one in your home, nor would you need one. They are useless to home users (that's you, faggot) because they don't do anything special for you. These quantum chips that cost millions perform worse than the latest AMD chips that are under $200. The power draw and heat generated by quantum computers is also fucking absurd, so enjoy your ten thousand space heaters in one room, dipshit.

If a quantum computer was suitable for normal computing, it still wouldn't be available to consumers.
It would pretty much put an end to all cpu companies out there.

What I think we're going to get next in this field for consumers is photonic cpus.

>"is X the *future*"
>"X isn't good at the moment stupid fucking faggot"

So toxic

remember when graphene was going to be a thing

The same was said about normal computers too. Was it some guy from IBM that said something like "There's a market for at most 5 computers worldwide"?

Back then computers were shit (compared to "the latest AMD chips that are under $200"), used tons of energy, produced tons of heat and took up a whole floor. So you're not making a good point by saying the same about quantum computers.

In maybe 20 years the problems will be solved thanks to room-temperature superconductors or whatever. And then people will start to use them professionally at first (probably as an add-on card as another user pointed out), but then as prices go down, they'll get popular for enthusiasts too, and as time goes by we'll have quantum chips in our future phones (just like we got 3D chips in them right now, for whatever reason).

The other thing it needs apart from a breakthrough in technology is to find why the hell a quantum computer would be useful. As others pointed out, a quantum computer isn't automatically 1000 times faster than a normal one. But quantum computers are orders of magnitude faster on some very specific tasks, like finding if an element is part of a list or factorizing numbers. And since none of this matters very much for a personal computer, where its main task boils down to pushing pixels as fast as possible to the screen, I don't think we're gonna see personal quantum computers that soon.

>I don't know the difference between linear and quantum computing nor my mouth from my asshole
The post.

Can someone smarter than me give me the rundown on why this is? I'm trying to search for limitations and the reasons for it, but all that's popping up is clickbait claiming they'll allow us to break any encryption and hack into any computer and all this other bullshit.

A normal computer has bits that are either 0 or 1. These are run through logic gates that take set inputs of 0s and 1s and produce set outputs of 0s and 1s. By running the bits through the right logic gates in the right order you can calculate things such as adding two binary numbers together (pic related).

A quantum computer uses quantum bits that are in a superposition of 0 and 1. It is unknown what state they are in until they are measured. These are run through quantum gates that modify the probabilities of the quantum bits either being 0 or 1 and at the end they are measured to see what their states are. The quantum bits don't work like normal bits and the quantum gates don't work like normal gates. It all comes down to probabilities. There's a pretty good chance that the correct sequence of 0s and 1s will be produced at the end but it requires checking to see if they are indeed valid.

Whereas a normal computer will be setup to run through all the possible outputs one at a time in search of the correct answer, a quantum computer will be setup to output the correct answer but will only do so a small percentage of the time.

imagine telling someone they need to use 2 entire rooms just to cool their CPU and you telll me

They require several square meters of cooling equipment to function, not feasible for personal usage.

>my computer needs to run cooler than my freezer

It's too soon to tell anything. The techonlogy is still in its infancy. I imagine it will take off in the next few decades (due to demand and the fact that "traditional" computers are reaching their physical limit) , but that's only speculation. Quantum computers are hard to build and bulky, so I doubt they will ever be as available to us as our smartphones are, but there is the possibility that through cloud computing they may reach a greater userbase.

What advantage does having a bit being in a superposition of two states confer? Seems to add more confusion to me. Why not just use a conventional logic gate where you input a particular set of logic levels and get a defined level out every time without having to check anything.

I'm sure this involves some quantum physics mumbo-jumbo I don't really understand but I guess I'm just cynical old school EE.

You're telling me a probabilistic CPU wouldn't be perfect for ray tracing???

Not a physicist myself but my understanding is that if you have a question with 1,000,000 possible answers but only one is correct, a regular computer may have to check all 1,000,000 possible answers to find the solution. A quantum computer produces outputs in such a way that the correct solution has a 1 in 50,000 chance of occurring.

With questions where the possible answers are astronomical and impractical to search through each and every one, quantum computers have the advantage of being much more likely to find the solution within a reasonable period of time.

I can understand that general idea being useful but I'm not sure how it translates to digital logic. When you put data into something like an AND gate there are two or more inputs and one output and the actual device does not have to search through anything. It works based on entirely electrical principles and it shouldn't matter whether the AND gate has 2 inputs (2-bit) or 64 inputs it shouldn't take significantly longer.

On the gaining side of things a quantum computer can actually be very beneficial. My understanding of them is they consider every single outcome at once instead of every outcome one at a time. If this is the case then it can make AI exponentially better. The issue comes in actually having a quantum computer in your house, and to that end I don't think it's ever going to happen.

For general computer purposes, I think a quantum computer could be just as fast as a normal CPU, but that would be thrown away all of its advantages for the sake of general use

>what is math
>what are algorithms

I'm not a specialist, but I know that by definition, quantum computers don't work in binary, so traditional logic gates wouldn't work in them.

Well considering how easy a quantum computer could break cryptography if given enough power it could completely change how we do things in the future. The problem is how far into the future are we talking.

Personally I don't think quantum computers are going to be all too relevant for computing purposes until we have the servers located in space where we can hit temperatures lower than liquid helium. At that point they might be more viable than they are on earth because the colder they get the more accurate they get.

The problem with putting something like this in space is that if it generates any heat, it's much more difficult to dissipate it.

They in fact can't break most cryptography in the sense you are thinking about.

Its more of an issue of: Congrats, if you actually can keep a quantum computer operating perfectly with no errors (remember, its probabilistic though with more iterations you can make the result more certain), you reduced the time required to compute this from a hundred billion years to half - for some ciphers.

You have some engineering issues that's true but this is probably the closest thing to reality due to how cold space is. At least makes a bit more viable than it does on earth where liquid helium is an absolute bitch to make and even then it barely gets a cold enough to be viable.

You thinking of quantum computers today, not next year's not 10 years down the line quantum computers. Given time quantum computers are probably going to get to the point where the cryptography we have today is crackable in less than a week with infinitely less resources than it would to a traditional computer. This will probably force us to rethink how we even implement computer security in the coming years.They're not to be the change in the same way that smart phones were where everyone has one, or at least near everyone, but they are going to change how the world works.

(cont'd)
Also, we don't generally even want full all quantum computers. If they were arbitrarily miniaturizable they'd be some small part like a sse4 unit in a cpu.

They'll never be able to miniaturize them unless you can get temperatures near absolute zero without large refrigeration units, unless the fundamental way of quantum computer works can work at room temperature or above room temperature were never going to see them at home use levels.

Has nothing to do with it.

Unless we find something that acts very differently from quantums, you'd still need a 50 billion times bigger/faster machine (despite it still communicating anything at light speed at most, which seems basically impossible to me with a 50 billion times bigger thing) to get this done in a year.

It's kind of like how increasingly large sky scrapers don't quite put us in reach of equipping the whole galaxy with a dyson sphere on each (not consumed in construction) star.

Does anyone else think OPs pic (and CPUs in general) look like Protoss tech?

Fortunately, near absolute zero is no requirement.

This and surely a great number of other approaches also could work:

There might be a surprising number of ways to manipulate dem qbits as desired, and some of them may be very small even by necessity. We'll see.
