Quantum computing thread

[mostonhel]

And what? You think there aren't scammers and the likes in western scientific circles?

They basically exist every where, and if Pan Jianwei is one, he will be found out sooner or later (and if he is, then yes, he would have wasted resources/money/time etc.).

What? When did I say anything like that? Do you want China to become another America full of Elon Musks?
But at least you acknowledge the possibility that Pan could be a shamless money grabbing scammer, not like the one user who claims to be “fair and unbiased”.

And to be honest, If Pan and USTC can just be quiet and not try to shift China's focus on semiconductor, which is really crucial in this decade, to quantum technology which is another nuclear fusion that won't have any practical use in 50 years, they may get away with all those scams.

But right now, there are increasing strong voices in and outside China criticizing Pan and USTC quantum boys because they are trying to write textbooks. You already see in the US why you can't let special interest group control the country, these guys are even worse than NRA.

The whole reason why the global quantum computing hype started again in 2010's was because Moore's law died, computing power was barely increasing, and semiconductor R&D was producing diminishing returns. Quantum computing was a very attractive field because it offers potentially exponential increase in computing power. If semiconductors R&D returns were still very promising, do you think gov and private sector around the world would throw billions into quantum computing R&D?

The very foundation of semiconductor technology is built on our understanding of quantum effects, I'm doubting you actually understand all the stuff you are spewing out here. Quantum technologies are crucial to current and future chip development, especially since quantum effects dominate in the microscopic regime, which we are approaching in our lithography processes.

Be honest, why do you hate Pan so much? Did he steal your grant money? Did you lose money on the stocks of his company? Are you a professional trying to short his company?

Why do you have a hard-on for smearing Chinese physicists

No I don't. I just happened to know that back in the day, USTC physics students is notorious for having anime girls on their walls, dreaming of going to the US and actively being a fan of IJA/IJN on chinese renren.com. Really makes people wonder why USTC suddenly become so patriotic when it comes to quantum.

I don't think you understand quantum computing. You should google what is Quantum Supremacy first.

Quantum technologies are crucial to current and future chip development

Quantum technology will not have any pratical use other than the very little possibility of breaking RSA.
And this paper just proves that any quantum computing without an error correction mechanism can be easily surpassed by a traditional computer.

I glanced over the paper earlier, and came to the same conclusion. QAOA is already kind of sketchy, this paper is basically a quantum computing research group, which happens to already have a working "quantum computer" with a decent number of working qubits. They managed to convert parts of a new trendy unproven algorithm related to classical factoring into quantum language and ran a program on their fancy machine to publish a paper. Great paper in terms of hype, will probably get lots of citations, but won't really advance the field of quantum computing.

I agree with both Professor Lu Chaoyang and Enrique Solano. As Lu Chaoyang said NISQ is a plausible dead end so the focus should be on long term viability of QC. But this doesn't negate the fact that the algorithm developed by Professor Long Guilu and his team is the most advanced hybrid classical-quantum factorization algorithm ever. Moreover, they've left out key aspect of their research due security reasons. If they've enough funding they may go for the kill or they're on their way. The paper also tells about their hardware sophistication of circuit depth and particularly dimensional reduction which you alluded as fancy due to your lack of understanding.

Ok Wuhun, please explain what is enlightening and novel in this paper with regards to "hardware sophistication of circuit depth and particularly dimensional reduction" without being condescending, I'll wait.

Yea, no.

Even as I'm just an ordinary layman, even I can see, that it already seems like there's possible uses of quantum computers outside of 'just breaking RSA'.

So big disagree on that.

I don't know enough about quantum computing. I'm not a subject matter expert. But since Pan won multiple awards presumably awarded by subject matter experts, and Pan is an experimentalist so there's actual research data backing him, I believe it requires extraordinary and direct evidence to call him a fraud.

Unless you think the west is awarding him solely to divert China's attention, the fraud theory doesn't seem to hold up to evidence.

Yes, there have been noted failures and other ideas which haven't worked, but they haven't actually cost very much.
But Elon Musk has created SpaceX and Tesla, which are basically entirely new industries of the future (in the USA) worth trillions.

If you had more Elon Musks, you'd have more trillions

Yea no, China definitely doesn't want more Elon musks.
