so i guess the next bit after 64 cpu is qu-bit, quantum bit

Quantum computers won't displace traditional computers. There's certain niche use-cases for which quantum computers can become wildly faster in the future. But for most calculations we do today, they're just unreliable. So, they'll mostly coexist.

In other words like GPUs. GPUs suck ass at complex calculations. They however, work great for a large number of easy calculations, which is what is needed for graphics processing.

Presumably you’d have a QPU in your regular computer, like with other accelerators for graphics etc, or possibly a tiny one for cryptography integrated in the CPU

There would have to be some kind of currently unforseen breakthroughs before something like that would be even remotely possible. In all likelihood, quantum computing would stay in specialized data centers. For the problems quantum would solve, there is really no advantage to having it local anyways.

I assume we need a lot of breakthroughs to even have useful quantum computing at all, but sure.

Isn’t quantum encryption interesting for end users?

[–] [email protected] 5 points 4 months ago (1 children)

Quantum encryption isn't something quantum computers can even do. It's not just transforming bits into other bits, it's about building entirely new security properties based on physical properties of matter.

So, even if it is interesting for end users, they would need dedicated hardware anyway.

Shows how much I know! (Nothing)

Probably not in consumer grade products in any foreseeable future.
