>> No.59284256

I've heard that AES is not vulnerable to this, only RSA, because of some prime thingy. Also, you would need more qubits to be actually capable of decrypting RSA used in practice, so we are not doomed yet. If they could decrypt RSA, everyone would be freaking out right now.

there's only like 1000 people who do. everyone else memorizes high level concepts which are actually not completely accurate.

my (oversimplified) understanding is: quantum computers use qubits instead of bits. qubits have a third state besides "on" and "off" (the two states of a bit). this state is the superposition, which is like being both on and off at the same time. somehow these qubits allow us to write algorithms that can solve specific problems much faster than a classical computer.

i don't think so. the advantage isn't the fact that there's a 3rd state, it's the fact that you can use certain quantum properties of a superposition. quantum algorithms use complex math that you likely won't understand unless you're a physicist.

That's not really right. It's more like a probability of being on/off. You can poke it and modify it in various ways but it collapses and becomes binary as soon as you try to find out what its value is.

His point is that comparing quantum computers to the normal ones is comparing apples to oranges. They are better at some specific tasks, but won't necessarily yield a performance increase in normal everyday tasks, not to mention the fact that they probably cost an arm and a leg, and that their cooling uses a fuckton of power.

>> No.59287153

It takes an enormous amount of time and energy to use these things. And they aren't proven to be more efficient than a classical computer at many compute tasks yet.

You need a truly massive workload that has the potential for quantum speed up (like breaking RSA or calculating discrete log) to justify the latency overhead.

Thats why IBM is asking people to figure out how to program a quantum computer. There is no real killer app for quantum computing, outside quantum simulation.

Holy fucking shit, quantum computers rely on the probabilistic nature of particles or whatever, but their output is not probabilistic. If it was, it would be entirely useless. For example, if you were to do something that requires multiple iterations, the probability of your end result being correct would exponentially go down to zero.

>> No.59303726

>I'm not sure why you say that
When I wrote that post, I assumed that they would not be better at cracking hashes than a normal computer at all. Turns out I was partially wrong. Apparently, there is an algorithm called Grover's algorithm that cuts down search time from N to sqrt(N) for tasks such as hash cracking, however that increase is not as significant as the increase with Shor's algorithm (used to crack RSA), that reduces time from sub-exponential to polynomial (sub exponential time is better than exponential, but still grows worse than any possible polynomial)

They would probably crash the bitcoin market with that, and it would become useless pretty fast, I mean, who would use bitcoins after IBM mines a gorillion, and if no-one uses a currency, it is worthless. Not to mention that someone else would invent another quantum computer, and then they would have to race against other quantum computers, i.e. they would be basically back to where they started. Finally, the quantum computer market may be worth more than all the bitcoins in existence, which is around 20 billion dollars at the current rate.
