Quantum computing thread

Uhh what? Pan Jianwei team did not participate in that specific paper.

He's the main reason USTC can get away with so many lies.

He's the main reason USTC can get away with so many lies.

Then why did he win the Fresnel Award in Optics from the EU and his supervisor using his work won the Nobel Prize? They're all dumb?

When China desperately needs investment in real technology, in engines, in semiconductors and biotech, Pan Jianwei and USTC‘s whole quantum nonsense just can't stop scaming chinese government's money.

This is Scott Aaronson saying by the way. Scott Aaronson!

What does this mean? Very simple, computer computing without quantum error correction is just a scam.

Can't believe quantum computing still hasn't become another nuclear fusion already.

Scott Aaronson is just a highly respected theoretical quantum computing researcher, but don't take his positions as gospel. Likewise Pan Jianwei also is highly respected in the optical quantum computing community. Both researchers have their goals and try to fight for prestige and funding.

Although Pan Jianwei's current research may not result in a useful quantum computer, he's doing a lot more for China's science community than Scott Aaronson. Getting funding by overpromising but developing a strong research base in new tech field is still very important.

You should be a national treasure. DUDE. It's the exact opposite.

Getting funding by overpromising but developing a strong research base in new tech field is still very important.

Then it should be things like photonic chips, but they are still in relatively early stage of development. This kind of technology needs 10 more years of investment and is exactly the kind of horizon that warrants government help. Not a dead end like quantum technology and nuclear fusion.

Hype around quantum computing recedes over lack of practical uses​

Receding hopes for early benefits from quantum computing have already contributed to a sharp fall in the stocks of a handful of companies that rode the wave of enthusiasm over the sector to go public since the middle of 2021.

Based on their peak share prices soon after they each went public, Arquit, IonQ, D-Wave and Rigetti reached a combined value of $12.5bn. That has since fallen to $1.4bn. Among the events to batter the quantum companies last year, IonQ was hit by a report from a short seller claiming its technology did not live up to its claims, while Rigetti founder Chad Rigetti was removed as CEO before quitting the company late in the year.

Part of the problem facing the sector has been an excess of “hype” about the technology, said Constantin Gonciulea, CTO of advanced technology at Wells Fargo. He compared the build-up of expectations around quantum to the crypto industry, as many non-experts have been drawn into the field and promises for the technology have far outgrown its potential in the near term.

Despite this, companies working on the first quantum machines and software still insist that practical uses of the technology are just around the corner — while continuing to carefully avoid giving too precise a prediction about exactly when that will be.

David Rivas, head of engineering and product at Rigetti, said that the company still believed it would reach quantum advantage when its computers have “a few hundred to a few thousand qubits”. Even if they can’t match the performance of today’s supercomputers, they will still be useful if they cost much less, or if they can operate faster or with more precision, he said.

For some quantum companies, the startling Chinese claim about online encryption was a sign that the technology’s big moment is drawing neareri. But for the doubters, the apparent impracticality of the research will serve as confirmation that quantum computing is still an impressive science experiment rather than a practical technology.

Now you understand why all these ridiculous claims about breaking the RSA encryption.

To give people an example to understand these kind of things in scientific field.

Back in 2017, MIT professor Zhang Shousheng was really famous for the so-called Majorana Fermion and then opened a company called Danhua Capital. Most of this compnay's money comes from China Tsinghua University.
He committed suicide in 2018. Nobody knows why.

In 2021, Science retract the 2017 Majorana Fermion paper.

Readers who failed to reproduce the findings requested raw data files from the authors, which they provided. Subsequently, the provenance of the raw data came into question; additionally, an analysis of the raw and published data revealed serious irregularities and discrepancies. These issues have caused the editors at Science to lose all confidence in the conclusions of the paper, and we are therefore proceeding with an Editorial Retraction. Authors A. L. Stern, J. Wang, and B. Lian agree with this decision. Authors Q. L. He, L. Pan, X. Che, G. Yin, E. S. Choi, K. Murata, X. Kou, Z. Chen, T. Nie, Q. Shao, Y. Fan, K. Liu, J. Xia, and K. L. Wang disagree with this decision. Authors E. C. Burks and Q. Zhou did not respond. Author S.-C. Zhang is deceased.

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.).

Wait everything you wrote here was about the massive failure of western quantum computing companies. So the west wasted more money right?

Pan Jianwei is an experimentalist, very different from theoretician, because there's actually physical data behind his claims.

Where do you think the funding from photonic chips comes from? Grant applications with references tying photonic chips to the current hype technology, which was quantum technologies for the past 10 years.

Why do you have a hard-on for smearing Chinese physicists, Zhang Shousheng's theoretical contribution to the field of topological insulators is very impressive. He wasn't in the main group involved in that Majorana Fermion paper, why slander him?

If you are so impressive, why not show us your grant applications or papers/research projects you find worth funding in physics by China?
