can anyone dress the quantum computing FUD pls. does quantum computing really kill the crypto? is quantum computing even real?

Its currently still theoretical. If it becomes proven and real, there will be much much bigger problems resulting from it, that crypto will be at the bottom of the worry pile

With the current quantum computer, it will take about 10 billion years before they can hack a wallet.

For what, a measly pile of pixels? The computer itself probably will cost more, they will probably target government shit

EVERY. FUCKING. TIME. No, there will not be bigger problems. Every centralized service can move to post quantum encryption very quickly. Crypto can not.
>>28593926
Yes, because goverment secrets are openly accessible in the first place you fucking retard, nothing of importance is even connected to the internet.

quantum computing will hit crypto the hardest by far.

I was just reading a mainstream article about quantum computers in my own language. Apparantly its still incredibly hard to produce qubits and keep stable. At best they run for a millisecond iiuc. Anything done with a quantum computer currently can also be done with binary computing

No, it's not that you would get hacked. It's that the quantum computer would be able to solve all equations/encryption anything nearly instantaneously. That would make Bitcoin absolutely worthless. Because it no longer serves the purpose of the ledger.
>or something like that

[Anonymous No.28595610]

If crypto stays to the day quantum computing is available then it will certainly die and whoever owns a quant computer can sign transactions and steal everything. When quantum computing is made available, quantum encryption will be a thing too, so:
>cryptocurrencies are updated with quantum resistant algorithms and whatever doesn't just dies
In that case BTC would be dead or a fork/better version will emerge. Government and military can easily just migrate from post-quant algos, most, cryptos wont.

It could just mine and drive the supply up to some arbitrary level/totally maxed out and crush the price. The whole reason it works is because there's proof that a bunch of computers built consensus over the information encoded, but if one computer just does it all nothing is decentralized.

[Anonymous No.28598979]

yep, since matter on a quantum level can be in a superposition of states, qubits can be used to non-sequentially bruteforce encryptions that a classical computer wouldn't be able to hack in any reasonable amount of it.

One of which is crypto.
This is already being partially developed. So at some point some jew conglomerate will secretly build the first private qubit computer and hire some very talented russian hackers to design the software to use it. They will then be able to steal whatever amount of crypto they want from whoever they want. They will start this in secret. But its impossible to hide its happening. Once the rest of the world figures out whats happening
>where is my bitcoin

everyone will panic to sell and save their savings ASAP, the cryptocurrencies will crash in a day.

The biggest threat Quantum computing poses is that it could render all current encryption methods obsolete. Things like SSL encryption and Hashing algorithms. Quantum computing is still theoretical so in time as it's understood more new encryption methods will be designed. We are a long way off.

>quantum superposition
there's a lot of information on it. basically - if i throw a die in classical world, it can only end up on one side (lets say it lands on 4). but in quantum world, it takes up all possible values until we measure it
>how do you use it to compute on a regular binary system
well because of superposition, the calculations whose difficulty grows exponentially on classical computers - no longer grow exponentially with qubits. You can see that from teh dice thing I just said
>-how will Russian hackers know how to program on a completely different architecture with no functional os
You dont need a new OS. you can use existing OS, you just need new software. It's like with current processors where you have multithreading and 64-bit-architecture - you didnt need new OS, old one work fine. But if you want to fully use new capabilities, you need to design applications that use them.

>quantum superposition
Normal computers work with transistors, which move electrons to different places in the computer, when a transistor has a certain electron voltage, it reads 0, and when it doesn't it reads a 1, and that eventually does all the computing, so the transistor is always either at said voltage in which case it reads one bit or the other, a program is just basically, a set of instructions you give the computer so it will move electrons at different voltages in different transistors. A Superposition state is a state that only coherent matter (that is, material with a non-collapsed wavefunction) can have, which usually mean individual particles, atoms, or at most, molecules (which is as far as we've gone), it basically means a particle, or group of particles can have, instead of a "either this voltage, or this other voltage" a probabilistic voltage, so it would be "50% this transistor is in this voltage, hence 1, and 50% this transistor is in this voltage, hence 0", the key here is that this is not a matter or lack of information, according to certain experiments (Bell Inequality experiments) the system trully is 50% a 0-bit and 50% a 1-bit. This is called a qubit, or q-bit.

You can eventualy decohere this state, by measuring the q-bit (that is, using some form of disturbance on the system, like shooting a photon into it, which will collapse the wavefunction, and make the transistor be either in a 1 or a 0, as a regular system), but the key is that while the system doesn't collapse or decoheres, it can hold BOTH the 0 and 1 which means it can run programs much, much faster. Technically, anything a quantum computer does can be done by a regular computer, since both follow raw Turing computation laws, but a quantum computer can actually hold the double of information, and run even faster.

>how do you use it to compute on a regular binary system
Using Shor's algorithm. Shor's algorithm is a mathematical formula that could solve one of the keys of crypto, and of most cryptographic systems: the factorization problem. Basically, most cryptographic systems make a big-ass number, and then they have two other numbers (usually both prime numbers), which multiplication produce this big-ass number. The problem is that while you may hold one of this numbers as a public key, the other number could only be known by you, and there is currently no way of figuring out both numbers without taking like millions or thousands of years to get. Shor's algorithm is a way of exploiting quantum mechanics (using the q-bit trick) to solve a binary problem, in a reasonable time.

>how will Russian hackers know how to program on a completely different architecture with no functional os
Much of the theory is already actually laid down, like Shor's algorithm, or Grover's algorithm which could break many cryptographic systems, and many quantum computers follow the same raw-Turing-like-computer system, so it would be only a matter of going to the very basics of computation, which means making programs in the most primitive of languages, but it could be done with people with enough in-depth understanding of how a computer trully works, aided by a team of quantum mechanic experts for references.

The real problem of quantum computers is having a system that is big enough to hold large quantities of particles AND not make it decohere or collapse it's wavefunction. Quantum systems are really sensitive, and even a single beam of light can break the entire superposition.
