Is a quantum computer still a binary system?

Yea it just does it faster because every bit is both. Basically instead of processing the answer, all answers are already processed and you pick the correct one

what the fuck is that stupid leftie propaganda?

it's a memery system

>>56089905
it's alt-right propaganda tho

>>56089772
That sounds very silly.

>>56089958
quantum computer is fucking worthless for any realtime computation, especially those you'd have in an out of order execution unit, so expect it to hit the consumer market never.

>>56089905
tfw alt-right cant identify their own propaganda

>>56089734
No, it's ternary. 1, 0, or both :^)

>>56089958
It works great for breaking encryptions

Take PGP for example. The reason that public key cannot be used to decrypt, is that the computer basically need to figure out what two secret prime numbers are, based on the result of dividing them. When those prime numbers are many many digits, it takes forever. But with quantum computing, we instantly get all the possible answers, and within seconds we can confirm which is the correct answer.

It actually works well for others. It's counter intuitive, but having all possible answers availabe and picking the correct one is more efficient for a computer than figure out the answer (which is running each possibility for every cycle of the CPU until we get the correct answer)

How does that even work, though? Pick out the right answer? Makes no sense.

>Makes no sense.
it's just cutting edge science bro

>>56089983
Nope thats wrong

>>56089772
Almost right

In a classical computer system you have bits which are either 0 or 1. In a quantum computer system you have qbits which can be 0 or 1 or any value in between. The problem is that is is an internal state which cannot be read trivially. If you want to read the value of a qbit, you have to mesaure it which causes it to assume either the value 0 or the value 1 respecting the probabilites for these values. The trick in quantum computing is using the in between values to input all possible inputs to a problem at once and then use probability theory to make sure the correct answer has the highest probability at the end.

This makes most quatum algorithms (truly) non deterministic unlike all classical computers which are always fully deterministic.

This allows quantum computers to create true random numbers without resorting to the usage of external sources like thermal noise.

Well first you gotta learn quantum mechanics. We have found out that information doesn't exist unless observed. This is the schrodingers cat thing. If you wanna learn more in detail look up double slit experiment. Basically they did these experiments where electrons existed as waves of probability, and they only acted like normal matter when we were observing them.

So quantum computing is the same way, everything exists as a probability, we just have to constantly observe it, and every time we do, we get new results, this helps because the answer to the problem already exists, we just have to quickly observe the quantum processor until the right answer pops up.

Think of the current CPUs as a book. Say this book has a special page. With current tech we have to solve a really hard mystery which will take months and eventually the answer is page 68.

With quantum, we pick up the book and start flipping the pages quickly until we see the special page

>>56090107
How do we know which answer is right without doing all the work beforehand? What makes us stop on that exact value?

>>56090059
Which is easier: doing a complex problem and having to list the answer, or being given a complex problem and a multiple choice answer?

So in case of encryption, the computer can run all the possible keys, only one will produce a high percentage of real words. In other computing problems, im not so sure, but often times in computing, the result of a problem can always be confirmed as correct. So you can look at all results, and only one will come out as correct.professional non gaming Graphics cards already do this whole making sure the answer is correct thing. I think amd does that also. but keep in mind quantum computing isn't for everything, and at this point, it has certainty problems, meaning n answer correct with 60% certainty. IIRC just last week they got around 85 which was a huge milestone

>>56090173
85% wow that's absolutely abysmal. The Pentium FDIV bug caused something like 1 in every 10 billion calculations to be wrong and even that was considered unacceptable.

>>56089941
how can you tell?

>>56090213
he watches sargon videos

>>56090199
Yea exactly, that's why we don't have quantum computers in our rooms right now

>>56090218
So this is not what they believe?
I have no idea what gender even means anymore.
Is a woman who does a guy thing a man now?
Because then how the fuck are we ever going to fill quotas?
Eg. Girls who play magic are rare enough, calling them guys would be mean and then we won't have any girls at all.

>>56090199
Also keep in mind we've worked up to this number from single digits

>>56090253
Seems to me that there's not ever going to ever be 100% certainty, the issue seems to be with the principle of things, with how the data is interpreted afterwards being where improvements are made. but when the work isn't done to reach that point, you literally can never be sure can you? even if we get to within 99.997% accuracy that will still be useless for anything but cracking passwords.
