Are quantum chips supposed to replace the current CPUs and GPUs? Or are they supposed to be "just" another component that we connect to the CPU, the same way we connect GPUs?
QPU perhaps?

Re: Google plans to reach a Quantum Computing milestone before the year is out
#12When "reach a milestone in computing history" is written 4 times before getting to the content (hn title, article title, article summary, first sentence of article), the article feels a lot like click bait, which really discourages me from wanting to give it any of my time. Anyone want to write a tldr?
Re: Google plans to reach a Quantum Computing milestone before the year is out
#13I was excited to read this article up to the last sentence, a quote from the program manager “We’re trying to get support within Google, and this experiment has been very good to get other engineers talking to us.” to me, this statement negates much of the positive spin of the article. That said, the title does say 'stepping stone.' My primary professional interest is AI and quantum computing to pushing the field for…
I think a lot of computer scientists have a hard time believing quantum computers are possible. Not saying I agree, but I've heard this viewpoint a number of times.

#14I hope that doesn't finish as a "quantum bubble".

We are so far from talking about this that your question is nearly meaningless. Quantum computing has not even been demonstrated yet. This "quantum supremacy" is for a highly contrived algorithm and set up that has very little if any real world use cases. A generalized quantum computer able to run standard computing algorithms is very far in the future and so much basic research in computing science has to happen bef…
Pretty sure the only thing quantum computers are better at than classical computers currently is simulating quantum mechanics

What about quantum machine learning? assuming quantum computers become powerful tomorrow, won't they be useful in that field?

#18Wake me up when it's ready. For two decades we hear announcements that Quantum Computers are almost ready.
Yet beside bluffs and prototypes that require superconductor with very cold -230° C to do little, none of them resurfaced later.
Quantum Computers can be exiting and devastating. What happens if the first company/state keeps it a trade secrete and uses Quantum Computers without telling the rest of the world? (what if...) With Quantum Computers all the "secure digital stuff" of today can be broken, say good bye to your cloud online security. A good/bad actor can read everything. We should think about how to mitigate this issue, isn't it?

Martinis' group has laid out a plan to build a 49 qubit quantum computer that can solve a problem that is intractable for classical supercomputers with any known algorithm. If they pull it off we'll have the first provisional evidence that we can build quantum computers that can solve a problem classical computers cannot in a reasonable amount of time.
Caveats: it is possible there exists a superior classical algorithm that can solve the problem efficiently enough, and that we just haven't found it yet. It is also still within the realm of possibility that there exists an algorithm that can simulate any quantum computer with only polynomial slowdown, which would show quantum computers are not drastically faster for any problem.

#20Ah, now I can finally digitally simultaneously love and hate Google.
Just don't open the box, and we will all be fine.
