Scientist says greedy physicists have overhyped quantum tech

Nikita Gourianov, a physicist at Oxford University, yesterday published a scathing article full of wild, damning claims about the field of quantum computing and the scientists who work in it.

According to Gourianov, the quantum computing industry has been led astray by greedy physicists who’ve hyped up the tech’s possibilities in order to rip off VCs and get paid private-sector salaries for doing academic research.

Double, double

Per Gourianov’s article, the real problems started in the 2010s after investors started taking notice of the hype surrounding quantum physics:

As more money flowed in, the field grew, and it became progressively more tempting for scientists to oversell their results. With time, salesman-type figures, typically without any understanding of quantum physics, entered the field, taking senior positions in companies and focusing solely on generating fanfare. After a few years of this, a highly exaggerated perspective on the promise of quantum computing reached the mainstream, leading to a greed and misunderstanding taking hold and the formation of a classical bubble.

Gourianov’s entire premise seems to hinge on their assertion that “despite years of effort nobody has yet come close to building a quantum machine that is actually capable of solving practical problems.”

They illustrate their argument by pointing out that Rigetti, IonQ, and D-Wave (three popular quantum computing companies) combined have failed to turn a sufficient profit.

According to Gourianov:

The reality is that none of these companies — or any other quantum computing firm, for that matter — are actually earning any real money. The little revenue they generate mostly comes from consulting missions aimed at teaching other companies about “how quantum computers will help their business”, as opposed to genuinely harnessing any advantages that quantum computers have over classical computers.

Finally, Gourianov’s conclusion leaves no doubt as to their feelings on the subject:

Well, when exactly the bubble will pop is difficult to say, but at some point the claims will be found out and the funding will dry up. I just hope that when the music stops and the bubble pops, the public will still listen to us physicists.

Toil and trouble

In the words of the great Jules Winnfield, Samuel Jackson’s character from the classic film Pulp Fiction, “Well, allow me to retort.

I have but five words I’d like to say to Gourianov, and they are: IBM, Google, Amazon, Microsoft, and Intel.

I don’t think we need to do a deep dive into big tech’s balance sheets to explain that none of those companies are in any financial danger. Yet, each of them is developing quantum computers.

It’s unclear why Dr. Gourianov would leave big tech out of the argument entirely. There are dozens upon dozens of papers from Google and IBM alone demonstrating breakthrough after breakthrough in the field.

Gourianov’s primary argument against quantum computing appears, inexplicably, to be that they won’t be very useful for cracking quantum-resistant encryption. With respect, that’s like saying we shouldn’t develop surgical scalpels because they’re practically useless against chain mail armor.

Per Gourianov’s article:

Shor’s algorithm has been a godsend to the quantum industry, leading to untold amounts of funding from government security agencies all over the world. However, the commonly forgotten caveat here is that there are many alternative cryptographic schemes that are not vulnerable to quantum computers. It would be far from impossible to simply replace these vulnerable schemes with so-called “quantum-secure” ones.

This appears to suggest that Gourianov believes at least some physicists have pulled a bait-and-switch on governments and investors by convincing everyone that we need quantum computers for security.

This argument feels a bit juvenile and like a borderline conspiracy theory. Governments around the world have been working in tandem with experts from companies such as Google spinout SandboxAQ and IBM for several years to address the encryption issue.

No serious person involved in the decision-making is going to be confused about how math works because of crappy marketing hype or a misleading headline.

Gourianov’s rhetoric reaches a peak as they appear to accuse physicists of manipulating the hype around quantum computing out of sheer greed:

Some physicists believe, in private, that there is no problem here: why not take advantage of the situation while it lasts, and take the easy money from the not-too-sophisticated investors? Earning a private-sector level salary while doing essentially academic research is a pretty good deal, after all.

That’s quite the accusation.

Quantum computing bubble?

On the whole, however, it feels like Gourianov’s chief complaint isn’t that quantum computers don’t work, it’s that they aren’t very useful. Dr. Gorianov isn’t wrong. The technology is far from mature.

But make no mistake, today’s quantum computing systems do work. They just don’t work well enough to replace classical computers for many useful functions — yet.
