I've been reading about this Google quantum computer, and how its unreal performance proves the existence of the multiverse. Apparently, it solved a particular math problem in 5 minutes, compared with the 10,000,000,000,000,000,000,000,000 years it would take our fastest supercomputer to solve the same problem.

That's shockingly good performance. What I'd like to see now are some real-world applications. What does it look like when this quantum computer is tasked with mining Bitcoin? How long does it take to break AES-256?

These real-world tests would allow people to relate better than some abstract math problem. And I think it would light a fire under cryptographers, and motivate them to develop new quantum-resistant cyphers which will be absolutely essential if this sort of quantum processing is going to be the future of computing. Because right now, we're not prepared. #bitcoin

For some reason, that url is just redirecting to the main page. It's not pulling up the article you're trying to share.

From what I’ve read it’s not a threat.

I'm not sure what, exactly, that means, but if it's capable of breaking encryption, I consider it a threat. And even if this Google computer isn't eventually sold to other companies and people, it's a safe bet others won't be far behind. Including foreign actors. If this technology breaks encryption, and is released into the wild, it's a threat to us all.

I don’t know enough to debate this. Just what I read.

That's why I think they should run some practical tests on it. See what it can do with our modern crypto algorithms. Because if it can break AES-256, it can break the blockchain. And that's terrifying. These real-world tests should be run, and the public should be informed as to their capabilities.

Eventually it will crack. Everything is meant to crack at some point even tools like enigma was used to break German communication interception.

Question is when…..

RSA 2048 is supposed to be secure until 2030. RSA 4096 is supposed to be secure until 2100. I'm not sure about AES-256, but I'd expect it to remain secure until at least 2050. But that's not considering quantum computing. It's based on the anticipated progression of conventional computers. Quantum changes the landscape entirely.

We also as a people have to move in the direction as well in building quantum resistance computing. Not me but you know the very smart people.

Yeah, for real. I'm not doing that shit.
