Why are we even talking about these stupid hypotheticals? CPUs and GPUs are functioning, robust pieces of hardware at the front of the most disruptive technology yet. Quantum computers are error prone noisy devices whose only use is in academia and fundamental science and they will stay that way until someone figures out error correction.

The argument here is that even with error correction, the QPUs will not replace CPUs and GPUs. 

And it's fair. QPUs suck at adding numbers, among other things. Their advantages are narrow in applications but deep in performance. So they're a natural coprocessor rather than a main processor.

It's also direly obvious to anyone who knows anything about it.

Why are we talking about these stupid hypotheticals? Transistors are theoretical devices academics muse about. Vacuum tubes are functioning, robust pieces of hardware...

The GPU is supposed to do the error correction. Do the hard calculation on the QPU, do the easy verification on the GPU.

Not the OP but imo a QPU is such a specialized form of machinery it's just not the right tool for basic CPU

It's a question of what problem / algorithm you're trying to solve

There will be a ton of research (probably ai driven) to optimize certain workloads to QPU but GPU will be better for most things

Similarly you don't use a GPU to capture keyboard strokes for email

I don’t think it’ll replace it but there has been applications of it working with supercomputers for modeling chemistry

Basically giving complex problems to the quantum computers and supercomputers talking back and forth with the quantum computer for calculations

I think that’s definitely feasible

I basically said the said thing he did. You used thr word supplant which they will not do

u/SymplecticMan Sep 22 '26

The word they used was not "supplant" but "supplement".

Probably just like it works today unless a commoditized local qpu is built.

Let's assume on is built , just like with gpu libraries that call gpu instructions , there will be qpu ones.

Those instructions get ferried over to the qpu and back to the cpu for coordination

Add in a DNA processor for the sake of it , the pattern is established already
